## **1. Recommendations to Update to NCWM Publication 14 to Reflect Changes to NIST Handbook 44**

**Source:** NIST/WMD

**Background:** At its Annual Meeting in July 2005, the National
Conference on Weights and Measures (NCWM) adopted the following new or
modified requirements that will be reflected in the 2006 Edition of NIST
Handbook 44 and NCWM Publication 14. These items are part of the agenda
to inform the Measuring Sector of the NCWM actions and to recommend
changes to NCWM Publication 14.

**Recommendation:** The Sector was asked to review and, if acceptable,
recommend to the NTEP Committee adoption of the following changes to
Publication 14 based on changes to NIST Handbook 44:

### Checklist and Test Procedures for Retail Motor-Fuel Dispensers

               need not be indicated.]{.underline}**               
  -------------------------------------------------------------------------------

Discussion/Conclusion: The Sector reviewed the proposal and agreed that
the change was consistent with the requirements in NIST Handbook 44;
however, a manufacturer stated that a test method was needed to provide
uniform evaluations by various NTEP laboratories of the ability of a
device to meet the requirement. That manufacturer and an NTEP Laboratory
official agreed to develop a test method for review by the Sector on the
second day of the meeting. The Sector reviewed the proposed method and
agreed to add the following test method immediately following
Section 7.26 currently on page LMD 26 of NCWM Publication 14 and to
forward the amended proposal to the NTEP Committee as written for
consideration.

### Field Evaluation and Permanence Test for Vehicle Tank Meters 

Code Reference: N.4.2. Special Tests (except Milk-Measuring Systems),
N.4.5. Product Depletion Test, and T.4. Product Depletion Test

Product Depletion Test

Before vehicle-mounted applications are listed on an NTEP Certificate of
Conformance, the meter must pass a product depletion test. This policy
applies to all meter technologies (e.g.[,]{.underline} Coriolis mass
flow meters, turbine meters, [and]{.underline} positive displacement
meters) even if the meter will never be installed on trucks with more
than a single compartment. The permanence test still applies ~~to~~

least 20 days. Ideally, this test should be performed with a

**Purpose:** A product depletion test verifies the proper operation of
air elimination means when the storage tank for the product being
measured is pumped dry. This test is necessary for meters that may drain
a tank completely, such as a vehicle-tank meter.

Test Procedure:

For a multi-compartment tank:

Begin the test from a compartment (ideally the largest compartment)
containing an amount of fuel equal to or less than one-half the nominal
capacity of the prover being used. Operate the meter at the normal full
flow rate until the compartment is empty. There are several methods for
determining that the compartment is empty. There may be a significant
change in the sound of the pump. ~~Someone may visually watch for~~
[There may be visual evidence that]{.underline} the compartment ~~to~~
[has]{.underline} run dry. The meter may stop entirely or may begin to
move in jumps (pause, resume running, then pause, then run again.)

Continue the test until the meter indication stops entirely for at least
10 seconds. If the meter stops for 10 seconds or more, proceed to step
3. If the meter indication fails to stop entirely for a period
[of]{.underline} 10 seconds, continue to operate the system for 3
minutes.

Close the valve from the empty compartment, and, if top filling, close
the nozzle or valve at the end of the delivery hose. Open the valve from
another compartment containing the same product. Carefully open the
valve at the end of the delivery hose. Pockets of vapor or air may cause
product to splash out of the prover. The test results may not be valid
if product is splashed out of the prover. Appropriate eye protection is
required, but caution is still necessary.

Continue delivering product at the normal full flow rate until the
liquid level in the prover reaches the nominal capacity of the prover.

Close the delivery nozzle or valve, stop the meter, allow any foam to
settle, then read the prover sight gauge as quickly as practical.

Compare the meter indication with the actual delivered volume in the
prover.

Calculate the meter error, apply ~~special~~ **[Product
Depletion]{.underline}** test tolerance, and determine whether or not
the meter error is acceptable.

Test Procedure:

For a single-compartment tank:

The test of a single-compartment tank is easier to accomplish if there
is a quick-connect hose coupling between the compartment valve and the
pump that supplies product to the meter. If the system does not have a
quick-connect coupling between the compartment and the meter, an
additional source of sufficient product at the test site is required.

Without a quick-connect coupling:

1.  Begin the test with the compartment containing an amount of fuel
    equal to or less than one-half the nominal capacity of the prover
    being used. Operate the meter at the normal full flow rate until the
    supply tank is empty. There are several methods for determining that
    the tank is empty. There may be a significant change in the sound of
    the pump. Someone may visually watch for the tank to run dry. The
    meter may stop entirely or may begin to move in jumps (pause, resume
    running, then pause, then run again).

Continue the test until the meter indication stops entirely for at least
10 seconds. If the meter stops for at least 10 seconds, proceed to
step 3. If the meter indication fails to stop entirely for at least
10 seconds, continue to operate the system for 3 minutes.

Close the compartment valve and the delivery nozzle or valve if top
filling. Stop the pump and load sufficient product from the alternate
source into the supply compartment for the meter being tested. Allow the
product to stand in the compartment for a brief time to allow entrained
vapor or air to escape.

Open the compartment valve and restart the pump without resetting the
meter to zero. Carefully open the nozzle or valve at the end of the
delivery hose. Pockets of vapor or air may cause product to splash out
of the prover. The test results may not be valid if product is splashed
out of the prover. Appropriate eye protection is required, but caution
is still necessary.

Continue delivering product at the normal full flow rate until the
liquid level in the prover reaches the nominal capacity of the prover.

Close the delivery nozzle or valve, stop the meter, allow any foam to
settle, then read the prover sight gauge as quickly as practical.

Compare the meter indication with the actual delivered volume in the
prover.

Calculate the meter error, apply ~~special~~ **[Product
Depletion]{.underline}** test tolerance, and determine whether or not
the meter error is acceptable.

**With a quick-connect coupling**:

1.  During a normal full flow test run, close the compartment valve at
    approximately one-half of the nominal prover capacity. Then slowly
    and carefully disconnect the quick-connect coupling allowing the
    pump to drain the supply line.

2.  Continue the test until the meter indication stops entirely for at
    least 10 seconds. If the meter fails to stop entirely for at least
    10 seconds, continue to operate the system for 3 minutes.

3.  If the meter stops for at least 10 seconds or after 3 minutes, close
    the delivery nozzle or valve at the end of the delivery hose if top
    filling.

4.  Reconnect the quick-connect coupling and open the compartment valve.

5.  Carefully open the nozzle or valve at the end of the delivery hose.
    Pockets of vapor or air may cause product to splash out of the
    prover. The test results may not be valid if product is splashed out
    of the prover. Appropriate eye protection is required, but caution
    is still necessary.

6.  Continue delivering product at the normal full flow rate until the
    liquid level in the prover reaches the prover\'s nominal capacity.

7.  Close the delivery nozzle or valve, stop the meter, allow any foam
    to settle, then read the prover sight gauge as quickly as practical.

8.  Compare the meter indication with the actual delivered volume in the
    prover.

9.  Calculate the meter error, apply ~~special~~ **[Product
    Depletion]{.underline}** test tolerance, and determine whether or
    not the meter error is acceptable.

Discussion/Conclusion: The Sector reviewed this item and agreed that the
term "special test" should be changed to "product depletion test"
throughout the Product Depletion Test procedure of Section "C" Field
Evaluation and Permanence Test For Vehicle-Tank; Except for LPG,
Cryogenic, and CO~2~ Meters, on pages LMD 65 through LMD 68 in the 2005
Edition of NCWM Publication 14, to be consistent with NIST Handbook 44
Paragraphs N.4.5. and T.4. A manufacturer of aircraft refueling
equipment suggested that the exception in N.4.5. for devices used
exclusively for the delivery of aircraft fuel should be added to the
checklist. The Sector agreed that the first paragraph of the Product
Depletion Test should be modified as follows and the modified proposal
be forwarded to the NTEP Committee for consideration:

[Except for devices used exclusively for the delivery of aircraft
fuel,]{.underline} ~~B~~[b]{.underline}efore vehicle-mounted
applications are listed on an NTEP Certificate of Conformance, the meter
must pass a product depletion test. This policy applies to all meter
technologies (e.g., Coriolis mass flow meters, turbine meters, positive
displacement meters) even if the meter will never be installed on trucks
with more than a single compartment. The permanence test still applies
to include the throughput and with a duration of a least 20 days.
Ideally, this test should be performed with a multiple-compartment
vehicle; however, a single-compartment vehicle may be used to simulate
the product depletion test by running the tank empty if a
multiple-compartment vehicle is unavailable.

At the meeting this Agenda Item was combined with Agenda Item 4. (See
Agenda Item 4 for the conclusion.)

## **3. Acceptable Symbols or Wording to Identify Unit Price, Total Price, and Quantity on a Retail Motor-Fuel Dispenser**

**Source:** Maryland NTEP Laboratory

**Background:** At the June 2002 NTEP Laboratory Meeting, one of the
participating laboratories requested guidance on acceptable symbols or
wording to identify the unit price, total sale, and quantity delivered
on a retail motor-fuel dispenser. The laboratories recommended the
question be added to the 2002 Measuring Sector Agenda.

At the 2002 Sector Meeting, a work group was formed to address this
issue. No input has been received from the work group assigned to
develop this issue following the 2002 Sector Meeting.

At its 2004 Meeting, the Sector agreed the NTEP laboratories should
develop a list of acceptable symbols at the next laboratory meeting.

**Recommendation:** The NTEP laboratories submitted to the Sector the
following list of acceptable words and symbols for price and volume
declarations on RMFDs for inclusion in Publication 14:

**Discussion/Conclusion:** The Sector reviewed the proposed table and
agreed with the concept; however, some members believed that the letter
"l" (lower case L for liter) should be acceptable because it is
recognized and allowed in NIST Handbook 44, General Code Table 1.
Representation of Units. Another member was concerned that if something
was identified in the List of Price and Quantity Marking for RMFDs as
preferred, some NTEP laboratories might allow only those markings. The
Sector modified the Table containing the List of Price and Quantity
Markings for RMFDs as shown below and recommended the modified table be
forwarded to the NTEP Committee for consideration.

# New Items

## **4. Product Families for Positive Displacement (PD) Meters**

**Source:** Murray Equipment, Tuthill and Turbine Meter Work Group

**Background/Discussion:** During several NTEP evaluations conducted
since the last Sector meeting, concerns were expressed by manufacturers
that the family products table for positive displacement meters need to
be revised and updated to reflect changes in metering designs submitted
for evaluation and products currently found in the marketplace. One
meter manufacturer questioned the appropriateness of keeping aviation
fuel as a separate "Product Subgroup" when the physical characteristics
of those products are so similar to other refined products. Another
manufacturer wanted to know what testing was required to include
"biodiesel" on a CC (Certificate of Conformance). Another question asked
whether or not the evaluation must be conducted using biodiesel fuel
with the highest specific gravity available or could testing be
conducted using a product with very similar characteristics that is
available in the manufacturer's test facility?

**Recommendation:** Agenda Item 2 of the meeting agenda distributed
prior to the meeting contained a proposal for a family products table
for turbine meters. Agenda Item 4 contained two proposals for changes to
the family products table for PD meters. At the Sector meeting Items 2
and 4 were combined for discussion and consideration. The Sector
reviewed and discussed two alternative proposals for PD meters and the
proposal for turbine meters to determine if any of the proposals
contained appropriate recommendations for modifications to Section "C"
and the Product Family Table for Positive Displacement Meters in the LMD
Technical Policy of Publication 14. Two proposals were received to
address some of the issues for PD meters. The first proposal submitted
by Paul Glowacki (Murray Equipment, Inc.) is shown below as proposal
alternative number 1. The second proposal submitted by Maurice Forkert
(Tuthill Transfer System) is shown below as proposal alternative
number 2. The proposed family products table submitted by the turbine
meters work group is shown following proposal alternative number 2.

**Proposal Alternative Number 1:**

Proposal Overview

The driving factor behind this proposal is simplification of the
Positive Displacement (PD) Meter Product Family chart to more accurately
reflect the reality that PD meters are not sensitive to the differences
between typical products, but rather that viscosity and specific gravity
are the determining metrological considerations.

Thus, the product families are simplified to group liquids in one large
category (Normal Liquids) and several additional categories for
specialized liquids where other factors are considered.

There are four components to this proposal. Part I is the revised
product family table itself to replace the one currently in Pub 14.
Part II contains revised language that covers the requirements for
testing meters for new certificates according to the table. Part III
provides language for the requirements to convert existing certificates
to the new proposed categories. Part IV provides revised language to
harmonize certain requirements for vehicle-tank meters and stationary
meters.

**Part II**

**Proposed Language For Product Family Requirements**

**C. Product Families for All Meters**

When submitting a meter for evaluation, the applicant must specify the
product or product group for which the meter is being submitted. To
cover a product group, NTEP tests must be conducted with two liquids
within the product group. Upon test completion, a range of specific
gravities/viscosities between the specific gravities/viscosities of the
two liquids attained within the product group will be covered on the
Certificate of Conformance (CC). The specific gravity/viscosity range
within the product group can be expanded by conducting an NTEP test with
a liquid of higher or lower specific gravity/viscosity than is covered
on the existing CC.

The above does not apply to the following product groups: compressed
gasses, compressed liquids, and cryogenic liquids. In case of these
product groups, only one liquid within each of these groups is required
to undergo an NTEP evaluation and, upon completion, the entire product
group will be covered on the CC.

> Multi-product applications in which the meter is to be used without a
> change to zero or calibration to dispense different products must
> include a multi-product test if:
>
> \(1\) specific gravity varies by more than 0.1 for devices measuring
> in mass; or
>
> \(2\) viscosity varies by more than 1 cP (below 25 cP) for devices
> measuring in volume.
>
> The multi-product initial test will be performed on the meter without
> a change to zero or calibration using multiple products having a
> difference in specific gravity of at least 0.2 for devices measuring
> in mass and 2 centipoise for devices measuring in volume. For mass
> measuring devices which will be used to dispense products having a
> specific gravity range greater than 0.2 and for volume measuring
> devices which will be used for products having a viscosity range
> greater than 2 cP, the multi-product testing must be performed over
> the anticipated range before multi-product applications will be
> included on the CC. For the multi-product testing, throughput testing
> will be performed on one or more combinations of products; testing for
> the subsequent test will be conducted on all products used during the
> initial test without a change to zero or calibration. Multi-product
> testing requirements do not apply to devices used to dispense a
> product such as propane in which the product varies in normal
> operation.

**Proposed Requirements for Conversion of Pre-existing NTEP Certificates
of Conformance to New Requirements**

NTEP Liquid Measuring Device Certificates of Conformance issued before
2006, will be reclassified according to specific gravity and viscosity
ratings matching the Product Groups and corresponding Sub-Groups listed
on the existing manufacturer's Certificate of Conformance:

NOTE: In the event pre-2006 NTEP Liquid-Measuring Device testing was
performed on a single meter with products having a Specific Gravity
and/or Viscosity greater or lower than the Specific Gravity and
Viscosity of the reclassification, the product's actual Specific Gravity
and Viscosity can be used to meet the requirements for the 2006
manufacturer's Liquid Measuring Device Certificate of Conformance.

NOTE: A table of sample specific gravity and viscosity values for
typical products would be included in Pub 14. This is not included in
the proposal and would have to be developed at some point for inclusion
with the other changes.

EXAMPLES:

1)  Current Certificate lists a meter model approved for Solvents. The
    2006 classification is: Normal Liquids Specific Gravity 0.70 to 2.5
    and Viscosity 0.3 cP to 2500 cP.

2)  Current Certificate lists a meter model approved for Solvents and
    Agricultural Liquids. The 2006 Classification is: Normal Liquids
    Specific 0.70 to 2.5 Viscosity 0.3 cP to 2500 cP.

3)  Current Certificate lists a meter model approved for Solvents,
    Agricultural Liquids and Asphalt. 2006 Classification is Normal
    Liquids and Heated Products Specific 0.70 to 2.5 Viscosity 0.3
    cP to 2500 cP.

4)  Current Certificate lists a meter model approved for Asphalt and
    Solvents. 2006 Classification is Normal Liquids Specific Gravity
    0.70 to 2.5 Viscosity 0.3 cP to 2500 cP and Heated Products Specific
    Gravity 0.8 to 1.2 Viscosity 25 cP to 2420 cP.

**Part IV**

**Revised Language for Vehicle-Mounted and Stationary Meter Application
Requirements**

Publication 14 LMD Section R, page 8

Vehicle-Mounted and Stationary Applications of the Meter

If a meter evaluation is conducted in a vehicle-mounted ***or***
stationary application and the meter successfully meets the NTEP
accuracy and performance requirements for both vehicle-mounted and
stationary applications, then both applications can be included on the
NTEP Certificate of Conformance.

**Proposal** Alternative Number 2:

This proposal is based on several factors:

A)  Level playing field. The regulation should not be dependent on the
    type of liquid-measuring device. All types of liquid-measuring
    devices should be required to meet the same regulation or not be
    approved. I am proposing this Family of Liquids for all types of
    liquid-measuring devices.

B)  End use of a liquid is not a metrological issue. It is not an issue
    of measurement if vegetable oil ends up on the dinner table or in
    the crankcase. My proposal does not recognize the end use of a
    liquid. The marketplace regulations take care of that aspect.

C)  The effect of a measuring device on a liquid is not a metrological
    issue. The viscosity/specific gravity can affect the performance of
    a meter. It is a marketplace issue if the liquid is Newtonian,
    Thixotropic, Dilatant, Colloidal, or Rheopectic.

D)  Liquid-measuring devices that are approved for a range of
    viscosities/specific gravities may encounter liquids with solids in
    that range. The marketplace will be quick to eliminate the measuring
    device if the measuring device is not able to handle the solids.

E)  This is a move to bring our regulations closer in alignment with
    Canada and OIML regulations.

**C. Product Families for All Meters**

When submitting a meter for evaluation, the applicant must specify the
product or product group for which the meter is being submitted. To
cover a product group, NTEP tests must be conducted with two liquids
within the product group. Upon test completion, a range of specific
gravities/viscosities between the specific gravities/viscosities of the
two liquids attained within the product group will be covered on the
Certificate of Conformance (CC). The specific gravity/viscosity range
within the product group can be expanded by conducting an NTEP test with
a liquid of higher or lower specific gravity/viscosity than is covered
on the existing CC.

The above does not apply to the following product groups: compressed
gasses, compressed liquids, and cryogenic liquids. In case of these
product groups, only one liquid within each of these groups is required
to undergo an NTEP evaluation and, upon completion, the entire product
group will be covered on the CC.

Multi-product applications, in which the meter is to be used without a
change to zero or calibration to dispense different products, must
include a multi-product test if:

a)  specific gravity varies by more than 0.1 for devices measuring in
    mass;

b)  viscosity varies by more than 1 cP (below 25 cP) for devices
    measuring in volume.

The multi-product initial test will be performed on the meter without a
change to zero or calibration using multiple products having a
difference in specific gravity of at least 0.2 for devices measuring in
mass and 2 cP for devices measuring in volume. For mass measuring
devices which will be used to dispense products having a specific
gravity range greater than 0.2 and for volume measuring devices which
will be used for products having a viscosity range greater than 2 cP,
the multi-product testing must be performed over the anticipated range
before multi-product applications will be included on the CC. For the
multi-product testing, throughput testing will be performed on one or
more combinations of products; testing for the subsequent test will be
conducted on all products used during the initial test without a change
to zero or calibration. Multi-product testing requirements do not apply
to devices used to dispense a product such as propane in which the
product varies in normal operation.

The turbine meters work group proposed amending Section "P" of the LMD
Technical Policy in Publication 14 to add the following:

**P. Product Families for Turbine Meters**

To facilitate the certification of turbine meters, product family groups
have been created to eliminate the necessity of testing each product
individually. Turbine meter product groups are defined by viscosity,
density, lubricity, and chemical/physical compatibility.

When submitting a turbine meter for evaluation, the applicant must
specify the product or product group(s) for which the meter is being
submitted. A meter that is successfully tested on one product will be
approved for use with that product only. If the meter is successfully
tested on a lower viscosity product and then successfully tested on a
higher viscosity product in the same product group, then all products in
that group falling within the range of viscosities can be included on
the Certificate.

Bi-directional turbine meters must be tested in "forward" and "reverse"
flow directions. Turbine meters must be tested in the mounting
orientation(s) required. Horizontal/vertical-mounted turbine meters must
be tested in both horizontal and vertical orientation, and in "forward"
and "reverse" flow, if they are bi-directional. Vertically-mounted
turbine meters that flow in only one direction must be described in the
Certificate.

The flow range of turbine meters is affected by line size, viscosity,
and specific gravity. Therefore, the criteria for inclusion of meters
from 50 % to 200 % min/max flow rate of the meter tested cannot be
applied to all line size, viscosity, and specific gravity requirements,
with respect to turbine meters.

One method to include smaller line sizes with higher viscosities is to
use multiple meter factors to linearize the performance curve.

Another method to include smaller line sizes with higher viscosities is
to increase the minimum flow rate.

The following calculation can be used to determine if a smaller line
size needs adjustment because of viscosity. The method of adjustment
must be described in the Certificate.

Sizing Ratio = Liquid Viscosity (centistokes) / Nominal Line Size
(inches)

Sizing Ratio = 1 or less, use the normal 10 % minimum flow rate. (10:1
turndown)

= Above 1 to 1.5 use 20 % minimum flow rate. (5:1 turndown)

= Above 1.5 exceeds the Minimum Discharge Rate of Wholesale Devices and
cannot be included.

Multiple meter factors can also be used to achieve extended flow rate
and to linearize the performance curve with low and high specific
gravity applications. This use must be described in the Certificate.

The product or product group(s), meter orientation, and flow directions
covered by the Certificate are to be identified on page 1 of the
Certificate of Conformance. More detailed information, including typical
products to be covered, number of meter factors required for smaller
line size, higher viscosity, low/high specific gravity and extended flow
rate are to be included in the application section of the Certificate.

The source for some of the viscosity value information is in the
Industry Canada -- Measurement Canada "Classification of Liquids for the
Approval of Liquid Meters", Bulletin V-16 (rev. 2), Issue Date:
2005-05-13 Effective Date: 2005-07-01

Discussion: On the first day of the meeting, because of the common issue
presented in the proposals, the Sector agreed to combine Agenda Items 2
and 4 for discussion. One manufacturer of RMFDs stated that the
proposals in Item 4 to include alcohols in the product group of "normal
liquids" that also included water, petroleum products, chemicals, and
vegetable oils was not appropriate. Another manufacturer stated that if
a company could make a single device that can pass type evaluation for
both alcohols and petroleum products, that company should not be
penalized because another company must submit different models to
measure each product. After considerable discussion it was apparent that
while each of the proposals had merit, no individual proposal satisfied
all of the concerns of the members. It was suggested that the parties
responsible for each of the proposals and other interested parties meet
after the conclusion of the first day of the Sector Meeting to work on a
compromise document that would satisfy all participants.

Conclusion: On the second day of the meeting the volunteer group
presented a proposal for consideration by the entire Sector membership
present at the meeting. After a few minor editorial changes, the Sector
agreed to forward proposed revisions to NCWM Publication 14 Section "C"
Product Families for Positive Displacement (PD) Meters, Section "D"
Product Families for Mass Flow Meters (MFM), and a new Product Families
Table designed to include product family testing requirements for PD
meters, MFM, and Turbine Meters in a single table, as shown below, to
the NTEP Committee for consideration.

C. Product Families for ~~Positive Displacement~~ Meters

**When submitting a ~~positive displacement~~ meter for evaluation, the
manufacturer must specify the product family and ~~subgroup(s)~~
[critical parameters]{.underline} for which the meter is being
submitted. ~~From the list of liquids constituting a product family and
subgroup, at least two liquids representing of the high and low key
characteristics of that subgroup are to be selected for use in the test.
If the meter successfully completes all accuracy and permanence tests
with these products, the resulting Certificate of Conformance will cover
the entire subgroup of the product family.~~**

The product family and the specific product subgroup covered by the
Certificate are to be identified on Page 1 of the Certificate of
Conformance. More detailed information, including the typical product
types found in the subgroup, is to be included in the Application
section of the Certificate.

D. [Additional Criteria for]{.underline} Product Families for Mass Flow
Meters

**~~When submitting a direct mass flow meter for evaluation, the
manufacturer must specify the product or product group for which the
meter is being submitted. To cover a product group, NTEP tests must be
conducted with two liquids within the product group.~~** When two
liquids of different densities are tested, the Certificate of
Conformance (CC) for the mass flow meter will cover approved liquids
with a specific gravity range from 0.1 above the highest specific
gravity tested to 0.1 below the lowest specific gravity tested. The
specific gravity range within the product group can be expanded by
conducting an NTEP test with a liquid of higher or lower specific
gravity than is covered on the existing CC.

**~~The above does not apply to the following product groups: compressed
gases, compressed liquids, and cryogenic liquids. In the case of these
product groups, only one liquid within each group is required to undergo
an NTEP evaluation and, upon completion, the entire product group will
be covered on the existing CC.~~**

Multi-product applications (that is, applications in which the meter
will be used without a change to zero or calibration to dispense
different products which vary in specific gravity by more than 0.1) must
include a multi-product test. The multi-product initial test will be
performed on the meter without a change to zero or calibration using
multiple products having a difference in specific gravity of at least
0.2. For devices which will be used to dispense multiple products having
a specific gravity range greater than 0.2, the multi-product testing
must be performed over the anticipated range before multi-product
applications will be included on the CC. For the multi-product testing,
throughput testing will be performed on one or a combination of the
products; testing for the subsequent test will be conducted on both
products without a change to zero or calibration. The CC for a mass flow
meter will cover multi-product applications where the specific gravity
of a single product, or multiple products, varies by the amount tested
throughout the entire approved specific gravity range of the meter.
Example: Where a meter has been tested and a certificate issued for
multi-product with one liquid having a specific gravity of 0.7 and
another liquid having a specific gravity of 1.0 and the meter is
subsequently tested to expand the range with a liquid having a specific
gravity of 1.6, the allowed variation of gravities covered by the CC
will be from 0.7 through 1.6. Multi-product testing requirements do not
apply to meters used to dispense a product such as propane in which the
density varies in normal operation.

## **5. Permanence Test for "Wholesale Meters" in Publication 14**

**Source:** NTEP Laboratories

**Background/Discussion:** At the 2005 meeting of the NTEP laboratories
it was noted that Publication 14 does not contain permanence test
criteria for wholesale positive displacement meters. The NTEP labs
developed the following proposal for submission to the Sector for
review.

**Recommendation:** The Sector reviewed the following proposal for
possible forwarding to the NTEP Committee for approval and addition to
the 2006 Edition of Publication 14.

**Proposal:** Modify Section D of the Publication 14 LMD Checklist as
follows:

D. [Initial Evaluation and Permanence Tests for Wholesale Positive
Displacement (PD) Meters]{.underline}

**[The following tests are considered to be appropriate for metering
systems on Wholesale PD Meters:]{.underline}**

1.  **[Four test drafts at each of five flow rates.]{.underline}**

2.  **[Only one meter is required for the initial test, after which the
    meter will be reevaluated for permanence. The minimum throughput
    criterion for these meters is the maximum rated flow in units per
    minute x 2000]{.underline}**

3.  **[Following the period of use, the tests listed above are to be
    repeated. All results must be within acceptance
    tolerances.]{.underline}**

Tests of Automatic Temperature Compensating Systems on Wholesale Meters
(Code Reference T.2.3.4.)

The difference between the meter error for results determined with and
without the automatic temperature compensating system activated shall
not exceed:

1\. 0.2 % of the test draft for mechanical automatic temperature
compensating systems; and

> 2\. 0.1 % of the test draft for electronic automatic temperature
> compensating systems.

The results of each test shall be within the applicable \"acceptance\"
or maintenance tolerance.

Repeatability on Wholesale Meters (Code Reference T.2.3.3.)

When multiple tests are conducted at approximately the same flow rate,
the range of the test results for the flow rate shall not exceed 40 % of
the absolute value of the maintenance tolerance, and the results of each
test shall be within the applicable tolerance. This tolerance does not
apply to the test of the automatic temperature compensating system.

Tests for repeatability shall include a minimum of three consecutive
test drafts of approximately the same size and be conducted under
controlled conditions where variations in factors, such as temperature,
pressure, and flow rate, are reduced to the extent that they will not
affect the results obtained.

## 

Discussion/Conclusion: A mass flow meter manufacturer suggested that the
throughput requirement should be replaced with a time requirement of 60
days between the initial evaluation and the permanence test. The NTEP
laboratories were opposed to that change because it did not include any
criteria for an amount of use between tests. After some discussion the
proposal for a 60-day time frame was withdrawn. Another member suggested
that the reference to the Canadian throughput requirement should be
removed because at this time there is no mutual recognition program
between the United States and Canada for meters. The Sector agreed that
the reference to Canadian throughput requirements should be editorially
removed from all permanence test section in NCWM Publication 14. The
Sector agreed to forward the proposal for test requirements for
wholesale meters to the NTEP Committee for consideration.

## **6. NTEP Tolerances for Meters with Different Flow Rates when Using Different Sized Provers**

**Source:** Maryland NTEP Laboratory

**Background:** During an evaluation of a high-gallonage RMFD with
marked flow rates of 60 gpm maximum and 12 gpm minimum, the Maryland
NTEP laboratory found that the actual flow rate on the lowest setting of
the automatic nozzle was 6 GPM. Several questions need to be addressed
regarding this situation.

N.4.2.2 (b) in the LMD Code states "Devices with a marked minimum flow
rate shall have a \"special\" test performed at or near the marked
minimum flow rate."

If a 10-gal test measure is used, what is the appropriate tolerance
applicable? Table T.2. in the LMD Code stipulates that the special test
tolerance is 0.5 %, which is 11.55 cu in on a ten-gal test draft;
however, there is a footnote that states that the applicable acceptance
tolerance for a special test when using a 10-gal test draft is
5.5 cu in. Which tolerance should be applied during an NTEP evaluation?
If a prover with a capacity greater than 10 gallons is used, does it
provide a tolerance advantage over tests conducted with a 10-gal test
measure?

G-T.1. (e) states that acceptance tolerances apply to all equipment
undergoing type evaluation. Does that mean that special test tolerances
are not applicable during NTEP testing?

At its 2005 meeting the Sector agreed to forward a proposal to modify
G-T.1. as shown below to the NCWM and Southern Weights and Measures
Association S&T Committees for consideration.

> **Proposal: Modify H44 Sec. 1.10 Paragraphs G-T.1. Acceptance
> Tolerances (e) and N.4.2.2. Retail Motor-Fuel as follows:**

**G-T.1. Acceptance Tolerances. - Acceptance tolerances shall apply
to:**

> **(a) equipment to be put into commercial use for the first time;**
>
> **(b) equipment that has been placed in commercial service within the
> preceding 30 days and is being officially tested for the first time;**
>
> **(c) equipment that has been returned to commercial service follow­ing
> official rejection for failure to conform to per­formance requirements
> and is being offi­cially tested for the first time within 30 days after
> corrective service;**
>
> **(d) equipment that is being officially tested for the first time
> within 30 days after major reconditioning or overhaul; and**
>
> **(e) equipment undergoing type evaluation [(special test tolerances
> are not applicable)]{.underline}.**

At the 2005 NCWM Annual Meeting, the Meter Manufacturers Association
(MMA) indicated that they had not understood that the proposal submitted
to the Committee from the Measuring Sector would only apply to all types
of liquid-measuring devices submitted for NTEP evaluation. The MMA
stated that without special test tolerances most meters, especially
those installed in vehicle-mounted applications, would not meet
tolerances for low flow tests during both field and NTEP evaluations.
The Committee agreed to make the proposal an information item to allow
the MMA and the Measuring Sector time to further develop the proposal
and resubmit it to the Committee for consideration.

Prior to the addition of Table T.2. to the Handbook 44 LMD Code in 2002,
the applicale tolerances in T.2.1. for "retail devices" including RMFDs
were the same for normal and special tests. Special test tolerances were
only applicable to "wholesale devices" measuring liquids other than
agri-chemicals and asphalt. The Sector was asked to consider a
recommendation that limits the application of special test tolerances in
the LMD code to only those devices where it was appliclble prior to
2002.

**Recommendation:** The Sector reviewed the following proposal for
posible forwarding to the NCWM S&T Committee for consideration along
with a recommendation that the NCWM S&T Committee General Code item to
amend G-T.1. be withdrawn.

**Proposal:** Modifty Table T.2. Accuracy Classes for Liquid-Measuring
Devices Covered in NIST Handbook 44 Section 3.30. as follows:

Discussion/Conclusion: The Sector reviewed the proposal that would
remove the special test tolerance for retail motor-fuel dispensers and
wholesale meters measuring agri‑chemicals and asphalt. The Sector agreed
that some devices measuring agri‑chemicals and asphalt should have a
special test tolerance. The current definition of "retail" in
Handbook 44 now applies to devices that, prior to 2004 when the
definition of "retail" was changed, would have met the definition for a
wholesale device because of their rated flow. When the wholesale devices
measuring agri-chemicals and asphalt were classified as "wholesale,"
they were permitted to have a special test tolerance. Those same devices
may now meet the criteria to be classified as "retail"; however they
should still be allowed to have a special test tolerance. The Sector
agreed to limit the proposal to only RMFDs and to forward the modified
proposal shown below to the NCWM S&T Committee for consideration.

## **9. Value of the Smallest Unit for LMD Code**

**Source:** WMD

**Background/Discussion:** In 2004 the definition of a "retail device"
in Handbook 44 was modified to include all devices used to measure
product for the purpose of sale to the end user. At that time the S&T
Committee believed all affected parties were aware of the proposal and
there was no opposition to the change. However, after the 2005 Edition
of Handbook 44 was published and distributed, WMD received a comment
from a weights and measures jurisdiction that routinely tests large
meters used to deliver fuel to fishing fleets and other large
ocean-going boats. The jurisdiction stated that the average delivery is
approximately 300 000 gal and may be as much as 1 000 000  gal. At the
present time value of the smallest unit of the indicated delivery for
these devices is 1 gal. Because the fuel is being delivered to the end
user, the jurisdiction believes this is a retail delivery and that
Handbook 44 now requires a smallest unit of delivery of not more than
0.5 L (1 pt) for these devices. WMD recommends a change to Handbook 44
is appropriate to recognize a larger minimum unit of delivery for large
fuel deliveries.

**Recommendation:** The Sector was asked to review the following
proposal and if it agreed, to forward it to the S&T Committee for
consideration. It was also suggested that as an alternative, the Sector
could decide it was more appropriate to form a work group to develop
suitability criteria for all meters, including such things as minimum
and maximum flow rate, minimum resolution, minimum measured quantity,
etc., for an application and forward the concept to the S&T Committee as
a developing issue.

**Proposal:** Modify Handbook 44, Section 3.30., S.1.2.3. Value of
Smallest Unit as follows:

> **S.1.2.3. Value of Smal­lest Unit.** - The value of the smallest unit
> of indi­cated delivery, and recorded delivery if the device is equipped
> to record, shall not exceed the equivalent of:
>
> \(a\) 0.5 L (~~1 p~~t [0.1 gal]{.underline}) on ~~retail~~ devices
> [making a delivery of less than 1 000 gal]{.underline};
>
> \(b\) 5 L (1 gal) on ~~wholesale~~ devices [making a delivery of
> 1 000 gal or more]{.underline}.
>
> This require­ment does not apply to manually operated devices equipped
> with stops or stroke-limiting means.
>
> (Amended 1983 and 1986)

Discussion/Conclusion: The Sector supported the concept of the proposal;
however, during the discussion of the item, a recommendation was made to
base the smallest unit requirement on meter size (marked flow rate)
rather than the size of the delivery. The Sector agreed and modified the
proposal as shown below. The Sector agreed to forward the modified
proposal to the NCWM S&T Committee for consideration.

**Proposal:** Modify Handbook 44, paragraph S.1.2.3. as follows:

> **S.1.2.3. Value of Smal­lest Unit.** - The value of the smallest unit
> of indi­cated delivery, and recorded delivery if the device is equipped
> to record, shall not exceed the equivalent of:
>
> \(a\) 0.5 L **(~~1 p~~t [0.1 gal]{.underline})** on **~~retail~~**
> devices **[with a maximum rated flow rate of 750 L/min (200 gal/min)
> or less.]{.underline}**
>
> \(b\) 5 L (1 gal) on **~~wholesale~~** devices **[with a maximum rated
> flow of more than 750 L/min (200 gal/min)]{.underline}.**
>
> This require­ment does not apply to manually operated devices equipped
> with stops or stroke-limiting means.

## **10. Value of the Smallest Unit for Vehicle-Tank Meters (VTM) Code**

**Source:** Maryland NTEP Laboratory

**Background/Discussion:** Paragraph S.1.1.3. in the VTM Code requires
the smallest unit of indicated delivery to be not greater than 0.5 L
(0.1 gal) for deliveries on meters with a rated maximum flow rate of
500 L/min (100 gal/min) or less used for retail deliveries of liquid
fuel and 5 L (1 gal) for all other meters (except milk-metering
systems). VTMs with rated maximum flow rates greater than 100 gal/min
are being introduced into the marketplace; however, the amount of the
increase in flow rate and the amount of product being delivered do not
warrant a tenfold increase in the required value of the smallest unit of
measurement.

**Recommendation:** The Sector was asked to review the following
proposal and consider forwarding it to the NCWM S&T Committee for
consideration.

**Proposal:** Modify Handbook 44, Section 3.31., Paragraph S.1.1.3.
Value of the Smallest Unit. as follows:

> **S.1.1.3. Value of Smallest Unit.** - The value of the smallest unit
> of indicated delivery, and re­corded delivery if the meter is equi­pped
> to re­cord, shall not exceed the equivalent of:
>
> \(a\) 0.5 L (0.1 gal) or 0.5 kg (1 lb) on milk-metering sys­tems
>
> \(b\) 0.5 L (0.1 gal) on meters with a rated maximum flow rate of
> ~~500~~ **[750 ]{.underline}**L/min (~~100~~
> **[200 ]{.underline}**gal/min) or less used for retail deliver­ies of
> liquid fuel, or
>
> \(c\) 5 L (1 gal) on other meters.

Discussion/Conclusion: The Sector reviewed a proposal to increase the
rated maximum flow rate criteria in S.1.1.3. from 100 gal/min to
200 gal/min. Some manufacturers of aviation refueling systems suggested
that these systems need a separate criterion due to the unique nature of
their application. The Sector agreed with the aviation refueler
manufacturers and agreed to forward the modified proposal shown below to
the NCWM S&T Committee for consideration.

**Proposal:** Modify Paragraph S.1.1.3. as follows:

> **S.1.1.3. Value of Smallest Unit.** - The value of the smallest unit
> of indicated delivery, and re­corded delivery if the meter is equi­pped
> to re­cord, shall not exceed the equivalent of:

**(~~c~~[d]{.underline})** 5 L (1 gal) on other meters.

## **11. Add Fluid Ounce to NIST Handbook 44, Section 3.30. Liquid‑Measuring Devices, Paragraph S.1.2. Units**

**Source:** NTEP Laboratories

**Background:** NTEP issued a CC for a liquid-measuring device that
displays its deliveries in fluid ounces. The device currently in use
always makes a delivery of 4 fl oz. A weights and measures jurisdiction
would not approve the use of the device stating that it did not comply
with S.1.2. in the LMD Code. Paragraph S.1.2. allows binary submultiples
of the liter or gallon; therefore an indication of 1/32 gallon would be
acceptable. The laboratories agreed that consumers would understand
4 fl oz better than 1/32 of a gallon and suggested the Measuring Sector
review the following proposal and consider recommending it to the NCWM
S&T Committee for adoption into Handbook 44.

**Recommendation:** Modify Handbook 44, Section 3.30, S.1.2. Units, as
follows:

> **S.1.2.** **Units. -** A liquid-measuring device shall indicate, and
> record if the device is equipped to record, its deliveries in liters,
> gallons, quarts, pints, **[fluid ounces]{.underline}** or
> binary-submultiples or decimal subdivisions of the liter or gallon.

(Amended 1987, 1994)

Conclusion: The Sector supported the proposal to modify S.1.2. and
agreed to forward the proposal a recommended to the NCWM S&T Committee
for consideration.

## **12. Reorganize Publication 14 to Clarify Tests of ECRs for RMFDs**

**Source: NTEP Laboratories**

**Background:** At the 2005 NTEP Laboratory Meeting, one of the
Measuring labs stated that the LMD section of Publication 14 was not
well organized. During an NTEP evaluation the evaluator must
continuously flip from one section of the publication to another to find
all the requirements applicable to the device under test. The lab also
stated that the evaluation of an ECR interfaced with a RMFD required the
use of both the ECR Checklist and the LMD Checklist in order to find all
the applicable requirements. The California laboratory volunteered to
provide a draft reorganization of LMD Checklist and a draft of a revised
ECR checklist with the applicable requirements added from the LMD
checklist. Drafts of the reorganized LMD checklist and the revised ECR
checklist are available from NIST WMD upon request.

**Recommendation:** The Sector was asked to review the drafts submitted
and, if agreeable, to forward them to the NTEP Committee for approval as
revisions to the 2006 version of Publication 14.

**Conclusion:** The Sector supported the concept provided all NTEP
laboratories and other interested parties conduct a thorough review of
the proposed changes before they are incorporated in NCWM
Publication 14. The NTEP Director, Steve Patoray, agreed to post the
draft changes as shown in Appendices A and B on the NCWM website.

## **13. Next Meeting**

The Sector discussed the time and location for its next meeting. The
Sector supported having its next meeting immediately prior to the annual
meeting of the Southern Weights and Measures Association which will be
held in Annapolis, Maryland. Maryland Weights and Measures offered to
host a tour of the Maryland NTEP facility in the morning of the first
day of the meeting.

## **14. Multi-point Calibration (linearization) for Meters**

**Source: NTEP Laboratories**

Background/Discussion: At the 2005 NTEP Laboratory Meeting, one of the
labs noted a concern that some meter manufacturers are using multi-point
calibration (linearization) to expand the range of flow rates for a
meter submitted for type evaluation. Neither Handbook 44 nor
Publication 14 prohibit or provide requirements for the use of
multi-point calibration for meters. The laboratories agreed that, if
multi-point calibrations are used during an evaluation, it must be noted
on the CC for the device and that installations must include that
feature. The laboratories also agreed that multi-point calibration
should only be used to extend the range of flow rates beyond a turn-down
ratio of 5 to 1. Any meter submitted for evaluation utilizing
multi-point calibration must be able to meet test requirements over a
turn-down ratio of 5 to 1 without multi-point calibration and then would
be tested using multi-point calibration to expand the range of flow
rates beyond a ratio of 5 to 1.

At the time of distribution of this agenda a specific proposal for
addition to Handbook 44 or Publication 14 had not been submitted by any
of the NTEP laboratories. This item is included on the agenda to alert
the members of a concern and to solicit input on the subject that may
appear as an agenda item at the next Sector Meeting.

Conclusion: The Sector discussed the concerns of the NTEP laboratories
and agreed that the use of multi-point calibration should be restricted
to only extending the turn-down range to a ratio of greater than 5 to 1.
During the meeting the Sector developed a modification to Section "G" of
the technical policy on page LMD -- 6 of the 2005 edition of NCWM
Publication 14 as shown below and agreed to forward the recommended
change to the NTEP Committee for consideration.

Modify Publication 14 Technical Policy Section G. Range of Data Points
as follows:

G. Range of Data Points

The number and types of tests to be run on devices covered under this
checklist are specified in the Checklist and Test Procedures section and
the Field Evaluation and Permanence Tests for Metering Systems section
of this checklist. However, if the NTEP laboratory feels that there is a
performance or other Handbook 44 related problem and provides reasons to
support this belief, the laboratory is given the latitude to require
additional testing.

[Multi-point calibration shall be blind and integral (programmed during
manufacture and not accessible in the field) to the measuring element or
it shall not be used to establish the minimum flow range required (5:1
or 10:1, etc., as required). Programmable multi-point calibration can be
used to extend the range of a system beyond the minimum range required
for the measuring element. The use of multi-point calibration to extend
the range will be noted on the CC.]{.underline}

## **15. Audit Trail Remote Configuration**

**Source:** NTEP Laboratories

**Background/Discussion:** At the 2005 NTEP Laboratory Meeting, one of
the labs noted a concern that some retail motor-fuel dispensers do not
meet the sealing requirements for Category 1 devices because of the
definition of remote configuration capability in Handbook 44. Remote
configuration capability is defined as "the ability to adjust a weighing
or measuring device or change its sealable parameters from or through
some other device that is not itself necessary to the operation of the
weighing or measuring device or is not a permanent part of that device."
The mechanism for changing blend ratios on some dispensers, while not
required for normal operation of the device, is not a "permanent" part
of the device.

At the time of distribution of the agenda a specific proposal for
addition to Handbook 44 or Publication 14 had not been submitted by any
of the NTEP laboratories. This item was included on the agenda to alert
the members of a concern and to solicit input on the subject that may
appear as an agenda item at the next Sector Meeting.

The Sector discussed NIST Handbook 44 codes for liquid-measuring devices
that do not have specific provisions for electronic sealing (i.e., audit
trails) in the code, such as the Vehicle-Tank Meters Code or the LPG and
Anhydrous Ammonia Metering-Devices Code. At the meeting, manufacturers
of these devices stated that they have designed metering systems with
electronic sealing capability with remote configuration capability. They
are currently seeking an NTEP Certificate of Conformance (CC) for these
systems. Currently the specific NIST Handbook 44 code for these devices
does not address electronic sealing, but it is recognized in the General
Code and under the provisions of G-A.3. Special and Unclassified
Equipment. Accordingly, NTEP has made an *ad hoc* decision to apply the
criteria in the LMD Code to these devices; however, the manufacturers
would prefer specific language similar to that in the Liquid-Measuring
Devices (LMD) Code. During the discussion, the Sector concluded that
some of these new applications and other applications currently in use
would have been classified as the former device Category 2 device.

Conclusion: The Sector agreed that the decision to remove Category 2
from the LMD Code and the Mass Flow Meters Code should be reversed and
that provisions for electronic sealing should be added to
liquid-measuring devices codes 3.30. Liquid-Measuring Devices, 3.31.
Vehicle-Tank Meters, 3.32. LPG and Anhydrous Ammonia Liquid-Measuring
Devices, 3.34. Hydrocarbon Gas Vapor-Measuring Devices, 3.35. Milk
Meters, and 3.38. Carbon Dioxide Liquid-Measuring Devices and agreed to
forward that proposal to the Committee for consideration. The technical
advisor, Dick Suiter, NIST, will develop the specific proposal for the
recommended change to each of the codes listed above.

## **16. New Product Application for Meters and Formula for the Proper Calculation of Relative Error**

(Note: This item was added to the agenda during the Sector meeting.)

**Source:** FMC Smith Meter

**Recommendation:** Amend Section "F" of the LMD Technical Policy in
Publication 14 as shown in the proposal below:

**Proposal:** If a manufacturer wants to add a new product to an
existing family of meters, the following criteria will be applied:

1.  If the accuracy class in NIST Handbook 44 for the new product falls
    within the same NIST Handbook 44 accuracy class or a more strict
    accuracy class than the most strict accuracy class covered on the
    Certificate of Conformance, the entire range of meters sizes will be
    covered for product tested.

2.  If the accuracy class in NIST Handbook 44 for the new product falls
    within a less strict NIST Handbook 44 accuracy class than the most
    strict accuracy class covered by the Certificate, the new product
    will only be covered for meters meeting the requirements of
    paragraph E, Meters Sizes to be included on a Certificate of
    Conformance.

> **[If the product being added is from a family of products that has
> been previously subjected to the permanence test, then the requirement
> for a permanence test may be waived provided the initial test of the
> product being added meets following conditions:]{.underline}**
>
> **[a) the results of the initial test were not questionable;
> and]{.underline}**
>
> **[b) multi-point calibration may not be used to add the new
> product.]{.underline}**

Make the following editorial change to NCWM Publication 14 LMD
Checklists to add the formula for the proper calculation of relative
error

**[Percent Error = \[(Indicated -- Actual) / Actual\] x
100]{.underline}**

**[Where "Actual" = the amount delivered corrected for appropriate
influence factors.]{.underline}**

**Discussion/Conclusion:** At the Sector meeting, FMC Smith Meter
requested that Section "F" be modified, as shown above, to allow the
addition of a new product to a CC that already includes product(s) from
the same product family as the product to be added. FMC Smith Meter also
suggested that the formula for proper calculation of relative error
should be added to all of the LMD checklists to provide uniformity
between the NTEP laboratories when calculating errors during NTEP
evaluations. The Sector reviewed the proposed change to Section "F" and
agreed to forward the proposal to the NTEP Committee for consideration.
The Sector also agreed that the formula for proper calculation of
relative error should be added to all of the LMD checklists to provide
uniformity between the NTEP laboratories when calculating errors during
NTEP evaluations.
