## 

**Conclusion:** The Sector reviewed and agreed to recommend to the NTEP
Committee adoption of the changes to Publication 14 shown above based on
changes to the 2007 edition of NIST Handbook 44.

# Carry-over Items:

## 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 the LMD Checklist and a draft of a
revised ECR Checklist with the applicable requirements added from the
LMD Checklist. The drafts of the reorganized LMD Checklist and the
revised ECR Checklist are in Appendices A and B, respectively. At the
2005 Sector Meeting, the Sector supported the concept, provided all NTEP
laboratories and other interested parties conducted a thorough review of
the proposed changes before they are incorporated into NCWM
Publication 14.

**Recommendation:** The Sector reviewed the drafts submitted and
received input from the NTEP laboratories for possible forwarding to the
NTEP Committee for approval as revisions to the 2007 version of
Publication 14.

**Conclusion:** The Sector discussed the reorganized checklists which
were reorganized with the intent to make them more user friendly.
Although the draft reorganized checklists have not been used
extensively, the NTEP laboratories had no problems to report. The Sector
agreed to forward the drafts to the NTEP Committee for inclusion in the
next edition of Publication 14.

## Add Magnetic Flowmeters to Product Family Table.

**Source:** Magnetic Meters Work Group (WG)

[]{.mark}

**Background:** At the 2002 Sector Meeting, a Work Group (WG) was formed
to address the issue of product family criteria. Prior to the 2003
Sector Meeting the technical advisor was informed that this WG was not
ready to present a recommendation; however the WG requested that the
item remain on the agenda for further development.

At the 2003 Sector Meeting, the Sector agreed that a new WG should be
formed to develop family product tables for Mag Meters for consideration
by the Sector at its next meeting. The members of the new WG are:
Charlene Numrych (Liquid Controls), Chair, Richard Miller (FMC); Joe
Buxton (Daniel Measurement & Control); Randy Byrtus (Measurement
Canada). Charlene volunteered to contact other manufacturers to invite
them to participate in the WG.

The WG formed at the 2003 Sector Meeting identified four Turbine Meter
manufacturers that could provide data on a variety of products measured
using this type of meter. For the 2004 Measuring Sector Meeting, only
one Mag Meter manufacturer of three manufacturers was identified as
having a certificate for products other than milk. No information had
been gathered regarding manufacturers of Ultrasonic Meters. The WG did
not have a proposal to present at that time, but planned to continue its
work. A new chairman was needed for the WG because Charlene Numrych
(Liquid Controls) was no longer available to perform that function. The
WG had nothing to provide for the 2005 Measuring Sector Meeting.

[]{.mark}

The WG is submitting a proposal to add Magnetic Meters to the Family
Products table with additional background information, for discussion at
the 2006 Sector Meeting.

The proposed Product Family table adding magnetic flowmeters has been
reviewed by manufacturer representatives holding magnetic flowmeter NTEP
Certificates of Conformance (CC). Those comments were included in the
organization of this proposal.

**Operation:** Magnetic flowmeters determine the velocity of an
electrically conductive liquid in a known diameter tube section of the
piping. The gross volumetric flow rate of the liquid is calculated in
the electronic transmitter. The delivered volumetric quantity is
displayed on the transmitter and/or scaled pulses are transmitted to a
compatible register.

**Influence factors:** The magnetic flowmeter determines the gross
volume. The magnetic flowmeter is not influenced by the density of the
liquid.

The magnetic flowmeter has no moving mechanical components that would
rely on close tolerances and capillary fluid action. The magnetic
flowmeter is not influenced by the viscosity of the liquid.

Magnetic flowmeters determine the velocity of electrically conductive
liquids. [The conductivity of the liquid must be above a minimum
threshold value determined in the engineered design of the flowmeter and
specified by the manufacturer. The value of the conductivity is not
significant to the determination of the volumetric flow
rate.]{.underline}

**The Product Family Table:** The table has been edited to add a column
for magnetic flowmeters.

The Water Mixes of Alcohol and Glycols and Water categories have been
combined for magnetic flowmeters. Juices and Beverages have been added
to this category.

The Agricultural Chemical Liquids and Chemicals categories have been
combined for magnetic flowmeters.

[Test D]{.underline} is required for Agricultural Chemical Liquids,
Chemicals, Water, Beverages and Juices. [The conductivity of the liquids
in these categories is not significant to the performance of the
magnetic flowmeter.]{.underline}

A new [Test F]{.underline} has been added that is specific to magnetic
flowmeters. Test F is required for liquids in product categories where
the liquids commonly have low conductivity. The manufacturer submits the
flowmeter to be tested at a specified conductivity. The specified
conductivity is listed on the certificate. All liquids [in the same
category with conductivity above the conductivity of the liquid tested
will be included]{.underline}.

**Recommendation:** The Sector will review the following proposal for
possible forwarding to the NTEP Committee for approval and addition to
the 2007 edition of Publication 14.

Add magnetic flowmeters to the Product Family Table as follows:

**Conclusion:** There was considerable discussion of the proposal to add
magnetic flowmeters to the Product Families table. Most of the
discussion centered on a determination of what product characteristics
were most important when evaluating a magnetic flow meter. The members
of the WG present at the meeting agreed that the most important product
characteristic is conductivity. During the discussion, a member stated
that the column for magnetic flowmeters could be simplified similar to
the column for mass meters. The Sector agreed and modified the Product
Families table to add Magnetic Flow Meters as follows:

## Value of the Smallest Unit for LMD Code

**Source:** NCWM S&T Committee

**Background/Discussion:** In 2004 the definition of a "retail device"
in NIST 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
Committee believed all affected parties were aware of the proposal and
there was no opposition to the change. The Committee had not considered
applications where very large deliveries are made to the end user,
typically at high flow rates. After the 2005 edition of the Handbook 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. Prior to the revision
of the definition of "retail," the value of the smallest unit of the
indicated delivery for these devices was permitted to be 1 gal. Most of
these devices have mechanical registers which make it impractical to
have a smallest unit of 0.1 gal at the high flow rates used for such
large deliveries. Because the fuel is being delivered to the end user,
the jurisdiction believes this is a retail delivery. However, with the
revisions to the definition of retail device, NIST Handbook 44 now
requires a smallest unit of delivery of not more than 0.5 L (1 pt or
0.125 gal) for these devices.

At its October 2005 meeting, the NTETC Measuring Sector developed a
proposal and agreed to forward it to the Committee for consideration.
The Measuring Sector believed that, because the maximum flow rate for
many applications has increased, 200 gal/min is an appropriate "break
point" for determining what the smallest unit of measurement should be.
At its October 2005 meeting, the SWMA agreed with the Measuring Sector's
proposal and recommended that the item move forward to the Committee.

At the 2006 NCWM Interim Meeting, it was suggested that the Committee
should revisit the discussion on suitability of liquid-measuring devices
that was discussed by the NCWM in 1991 through 1993. In these earlier
discussions, the NCWM was unable to reach a consensus on any changes to
NIST Handbook 44, and the item was withdrawn from the Committee agenda.
The Committee was informed that there was interest expressed at the
2005 NTETC Measuring Sector meeting in developing new criteria
addressing suitability as it relates to flow rate, minimum measured
quantity (MMQ), and the smallest unit of measure for applications using
liquid-measuring devices. The Committee encourages the NTETC Measuring
Sector to pursue development of suitability requirements for submission
to the Committee for consideration. In the meantime, the Committee heard
no opposition to Item 330-2 and agreed to present the item for a vote at
the 2006 NCWM Annual Meeting.

At the 2006 NCWM Annual Meeting, the Committee received input from
several manufacturers of aircraft refueling equipment that there is a
safety concern with stationary refueling systems that are capable of
delivering jet fuel through two different sized hoses at different flow
rates using two different meters. In this scenario, the operators of the
refueling facility want both meters to have the same unit of indication;
that is, 5 L or 1 gal. The Committee understood the concern, but was
reluctant to modify the recommendation based on the limited information
available at the meeting. The Committee believed that the aircraft
refueling industry should propose a change during the next Conference
cycle through the NTETC Measuring Sector and the regional associations.
However, the Committee recognized that a legitimate problem may exist
with existing jet aircraft refueling equipment and encouraged weights
and measures jurisdictions to consider safety implications before taking
official action on existing jet aircraft refueling devices that may not
meet the requirements of paragraph S.1.2.3. During the voting session,
there appeared to be concern that if this item was adopted, weights and
measures officials could be perceived as ignoring safety issues for
aircraft refueling. There was an evident lack of support for the item
without an exemption for jet aircraft refueling; therefore, the
Committee changed the status of Item 330-2 to an information item to
provide sufficient time for development of appropriate language to
address the safety concerns with jet aircraft refueling equipment. The
Committee requested that the Measuring Sector provide comments or
changes to the proposal as appropriate.

**Recommendation:** The Sector reviewed the following proposal and
provided comments to the S&T Committee for consideration at the 2007
NCWM Interim Meeting.

**Proposal:** Modify Handbook 44, Section 3.30., S.1.2.3. Value of the
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 pt~~[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.
>
> (Amended 1983**[,]{.underline}** **~~and~~** 1986**[, and
> 200X]{.underline}**)

See agenda Item 12.

**Conclusion:** The Sector continued to support its recommended changes
to S.1.2.3. as shown above but agreed to consider the addition of a
paragraph (c) to allow a larger minimum unit for aircraft jet refueling,
during the discussion of agenda Item 12.

# New Items:

## Product Families for Meters

**Source:** NTEP Director

**Background/Discussion:** During several NTEP evaluations conducted
since the last Sector meeting, there have been concerns that the Product
Families tables for meters needs to be revised and updated to reflect
changes in metering designs being submitted for evaluation and products
currently found in the market place. One meter manufacturer wanted to
know what testing was required to include "biodiesel" on a CC: Must the
evaluation be conducted using biodiesel fuel with the highest specific
gravity available or can testing be conducted using a product, with very
similar characteristics, that is available in the manufacturer's lab?

**Recommendation:** The Sector reviewed and discussed possible changes
to clarify the Product Families table for Positive Displacement Meters
in the LMD Technical Policy of Publication 14 to be forwarded to the
NTEP Committee for approval and addition to the 2007 edition of
Publication 14.

The NTEP Director, Steve Patoray, offered the following list of concerns
with the current Product Families table:

1.  The table as it currently exists is still very confusing.

2.  It is not clear which tests are actually required.

3.  Instead of the \"Tests\" being listed in the header of the table,
    they should be listed with each product group.

4.  Typical products should be listed in ascending order (if possible)
    based on one of the key characteristics or have a method to ID key
    characteristics.

**Conclusion:** The Sector agreed that it would be appropriate to
consider reorganizing the Product Families table by meter technology
considering the most important product characteristics for each. The
Sector formed a WG to develop a proposal for consideration at the next
meeting. The WG will work primarily through e-mail and conference calls.
The chairman appointed the following individuals as members of the WG:

## Table of Key Characteristics of Products in Product Families Table for Meters

**Source:** NTEP Director

**Background/Discussion:** Prior to the Sector Meeting the NTEP
Director, Steve Patoray submitted the following comments for Sector
consideration.

> This is a developing item. Probably all of you reading this know more
> about this topic than I ever will. I have had discussions with several
> different people on this topic over the past several months. The
> Product table in NCWM Publication 14 has been improved over the past
> several years. Currently, Mass Flow Meters have a key characteristic
> of specific gravity. PD meters have a key characteristic of viscosity.
> We list in the table numbers; however, these numbers are without
> reference. These are normally tied to some temperature. None is
> listed; also, there is no cross reference for anyone to identify what
> products might fall within those ranges. I had a very difficult time
> finding specific information on even some very basic products that we
> normally use in evaluations. Several of the folks on the sector helped
> to locate various tables and charts to help identify these values. The
> information in these charts varies for the \"same\" product.
>
> As an example of the potential confusion, there are both dynamic
> (absolute) and kinematic viscosity. The values for these are not the
> same for the same product; the unit for these, respectively, is
> centipoises (cP) and centistokes (cSt).
>
> Quoting from the Engineering Tool Box: The viscosity of a fluid is
> highly temperature dependent and for either dynamic or kinematic
> viscosity to be meaningful, the reference temperature must be quoted.
>
> In the table on page LMD-3 there are numbers for both Viscosity and
> Specific Gravity (S.G.) but no temperatures. While S.G. may not be as
> temperature dependant, some reference should still be cited.
>
> To expand on this in the table in the publication on page LMD-3, we
> have Test C which just states viscosity, while Test E states
> specifically kinematic viscosity. This may be very important for the
> device that uses these tests, but I would suggest that it be clarified
> and consistent. The use of just the term \"viscosity\" could be
> misinterpreted.
>
> What I am proposing is that this group considers listing [specific
> values]{.underline} for each of the typical products listed in this
> table. It may need to be a separate table. With this information, the
> NTEP evaluator would then be able to look to the chart and find the
> correct value for the critical characteristic. This could be listed on
> the CC and the range could clearly be identified. Additional products
> could be added as necessary when they are used for an evaluation. The
> main point is that the same values will be used.
>
> Also, there are four different product groups for crop chemicals.
> Without further information, this can lead to confusion.
>
> Trying to follow all of the special notes is very difficult.
>
> There still seems to be product families that are based on some other
> factor that is not specified, not just viscosity or specific gravity
> (first page of table); many of the different products' values overlap.
>
> This should be enough to get the discussion started. I hope that I
> have been clear in the fact that I would like to see this table
> continue to be revised and if possible condensed.

**Recommendation:** The Sector discussed the NTEP director's concern and
explored the concept of having a table of product characteristics. The
Sector considered appointing a WG to develop this item for presentation
and discussion at the next meeting.

**Conclusion:** The Sector agreed that further development of key
characteristics should be included in the tasks of the WG formed to
develop a new product families table approach, as discussed in agenda
Item 5.

## NTEP Checklist for Water Meters in Sub-metering Application

**Source:** NTEP Director

**Background/Discussion:** The NTEP Committee has asked the Measuring
Sector to consider and develop a checklist for residential water meters.
These devices will most likely be used for sub-metering. Several states
have recently contacted NTEP regarding these devices. California already
has evaluation and certification of these devices in their state. It is
recommended that the Sector review the procedures used by California and
rework them into a format acceptable to NCWM Publication 14.

**Comments from the California NTEP Laboratory:** California has found
an electronic version and copied the specific section. California uses
this as an EPO for field enforcement, follows the same guidelines in
approval, does three tests at three flow rates, and does check
repeatability. It also has a basic form you can print and do water meter
tests. This also follows Handbook 44 Sections 1.10 and 3.36.

In type evaluation, we have a procedure (not a checklist) but it is for
the evaluator and starts with application review and other directives
not pertaining to actual testing. We also have an electronic form, which
is specific for our provers, and as previously stated, follow the
testing criteria of the EPO. It probably would not take a whole lot of
work (I\'m guessing) to format it to the Publication 14 format.

The Sector members can review the California checklist for Domestic Cold
Water Meters in the attached Appendix C.

**Recommendation:** The Sector discussed the NTEP director's concern and
explored the concept of adding a checklist for evaluation of water
meters in sub-metering applications to Publication 14. The Sector
considered appointing a WG to develop this item for presentation and
discussion at the next meeting.

**Conclusion:** The Sector agreed that the best approach for developing
a Publication 14 checklist for water meters would be the utilization of
a WG made up of technical experts and other interested parties. The
members present at the meeting who volunteered to serve on the WG were
Dan Reiswig, California NTEP Laboratory; Jim Welch, Measurement Canada;
and Rodney Cooper, Actaris Neptune. The Sector chairman, Mike Keilty,
will also invite participation by water meter manufacturers AMR, Badger
Meter, and Neptune Water Meter Division.

## NTEP Checklist for LPG Vapor Meters in Sub-metering Applications

Source: NTEP Director

**Background/Discussion:** The NTEP Committee has asked the Measuring
Sector to consider and develop a checklist for LPG Vapor meters. These
devices will most likely be used for sub-metering. Several states have
recently contacted NTEP regarding these devices. California already has
evaluation and certification of these devices in their state. It is
recommended that the Sector review the procedures used by California and
rework them into a format acceptable to NCWM Publication 14.

The Sector members can review the California type evaluation checklist
for LPG vapor meters in the attached Appendix D.

**Recommendation:** The Sector discussed the NTEP director's concern and
explored the concept of adding a checklist for evaluation of LPG vapor
meters in sub-metering applications to Publication 14. The Sector
considered appointing a WG to develop this item for presentation and
discussion at the next meeting.

**Conclusion:** The Sector agreed that the best approach for developing
a Publication 14 checklist for LPG vapor meters would be the utilization
of a WG made up of technical experts and other interested parties. Dan
Reiswig, California NTEP Laboratory, will provide a list of vapor meter
manufacturers to be contacted for participation on the WG.

## Testing Electronic Indicators Using Simulated Inputs

**Source**: FMC

**Background/Discussion**: It was stated at the 2004 Measurement Sector
meeting that the reason for allowing fixed indicators to use simulated
inputs was the fact that durability testing was not required due to the
limited vibration associated with their intended use, and
vehicle-mounted indicators could not be tested with simulated inputs for
the same reason. The intended use was a severe environment; therefore,
testing in the field following the permanence requirements was needed to
test the durability of the device. In other words to make sure the
device would function in its intended environment without failures due
to its usage.

The rational of allowing simulated inputs for revisions to an existing
CC regardless of installation type is the fact that the device has
already undergone the durability phase of the testing. Software
revisions will not affect the durability of a device; software changes
do however affect the functionality of a device. Therefore, testing with
simulated inputs offers a sufficient test to verify software
functionality.

**Recommendation:** The Sector reviewed the following proposal for
possible forwarding to the NTEP Committee for consideration at the 2007
NCWM Interim Meeting.

**Proposal:** Modify Publication 14 Technical Policy Section U. as
follows: (LMD -- 9)

U. Testing Electronic Indicators ~~for Stationary Installations~~
Utilizing Simulated Inputs.

a.  When evaluating electronic indicators for stationary installations,
    submitted separate from a measuring element, indicators may be
    evaluated using simulated inputs (i.e., meter pulse, temperature,
    pressure, density, communications, etc.).

b.  [When evaluating electronic indicators (regardless of installation
    type) for revisions to an existing CC for metrological significant
    software revisions, indicators may be evaluated using simulated
    inputs (i.e., meter pulse, temperature, pressure, density,
    communications, etc.),]{.underline}

**Conclusion:** The submitter explained the background for the original
proposal as discussed above. A member asked if the current language in
"a." would prevent being able to do some testing with simulated inputs
and additional field testing using "live meter" input. During the
meeting the Sector developed new language for Publication 14 Technical
Policy Section U. as follows and agreed to forward it to the NTEP
Committee for addition to the 2007 edition of Publication 14.

**[U. Evaluating electronic indicators submitted separate from a
measuring element]{.underline}**

> **[When evaluating electronic indicators submitted separate from a
> measuring element, simulated inputs (i.e., meter pulse, temperature,
> pressure, density, communications, etc.) may be used as
> follows:]{.underline}**

1.  **[For the initial testing of the indicator.]{.underline}**

2.  **[For the evaluation of stationary indicators.]{.underline}**

3.  **[For software changes to a device with an existing
    CC.]{.underline}**

##  Next Meeting

**Recommendation:** The Sector was asked to discuss the time and
location for its next meeting.

**Conclusion:** The Sector discussed the time and location for its next
meeting and agreed that the meeting would be scheduled immediately prior
to the October 2007 SWMA Meeting, in Little Rock, Arkansas. The exact
dates were yet to be determined. The Sector also agreed that any items
to be included on the agenda for the 2007 Sector Meeting must be
submitted not less than 30 days prior to the meeting in order for the
agenda to be distributed to the membership at least 2 weeks prior to the
meeting.

# Additional Items for Discussion if Time Permits

##  Display of Quantity and Unit Price for Self-serve Aviation Dispensers

**Source:** Veeder-Root

**Background/Discussion:** The normal self-serve installation for
aviation fuels does not use an analog or digital "gasoline dispenser"
that simultaneously displays money and volume. In most cases the
self-serve user interface is a credit card console/controller that
handles the transaction. These devices are not set up for the
simultaneous display.

Aviation self-serve dispensing systems use a base meter-register that is
a PD meter with a mechanical register and pulser or an electronic
register with pulse output, or an industrial dispenser with volume only
and a pulse output. The meter-register part sends pulses to the credit
card console/controller. All three components including the
consol/controller have NTEP certificates.

In June, the State of Alabama Weights and Measures reviewed a couple of
planned installations and informed the installing company that the
equipment was "Retail Motor Fuel," and "simultaneous display of Quantity
and Sale was required." This started a series of exchanges of
information between several parties including two consol/controller
manufacturers, several equipment suppliers, and the State of Alabama.

The typical "retail gasoline dispenser" that has the display capability
is not designed in terms of materials of construction for aviation
gasoline or jet fuel, nor does it have the flow rate capacity. Higher
capacity diesel dispensers have the materials of construction problem.
Moreover, in jet fuel applications, the dispensers do not have the flow
rate capacity required.

There is one small company that assembles dispensers that could today
put together a unit to meet the materials of construction and minimum
flow requirements. Their NTEP certificate currently is for diesel and
gasoline on their simultaneous display dispenser. They could use the
appropriate aviation-approved materials of construction components for
applications up to 50 gpm and simultaneously display price and currency.
These units, however, are not now commonly used in the aviation
industry, which means the experience is not there for wide acceptance,
and would not be adequate for jet fuel flow rates.

**Recommendation:** The Sector reviewed the following proposal for
possible forwarding to the NCWM S&T Committee for consideration.

**Proposal:** Modify Handbook 44, Section 3.30., paragraph S.1.6.5.5. as
follows:

***S.1.6.5.5. Display of Quantity and Total Price.***

> ***[(a)]{.underline}** When a delivery is completed, the total price
> and quantity for that transaction shall be displayed on the face of
> the dispenser for at least 5 minutes or until the next transaction is
> initiated by using controls on the device or other customer-activated
> controls.*
>
> *\[Nonretroactive as of January 1, 1994\]*
>
> (Added 1992)(Amended 1996)
>
> **[(b]{.underline}**) **[For aviation fuel dispensing, the quantity
> and total price need not be displayed simultaneously as long as the
> total price and quantity delivered can be viewed by interacting with
> the display or controller, or the total price and quantity is
> available on a printed receipt as specified in S.1.6.7.]{.underline}**

Conclusion: The Sector reviewed the proposal to allow devices used in
aircraft refueling to either display or print the total price and
quantity delivered at the end of the transaction. The Sector took no
position on the proposal because most members did not feel qualified to
make an informed recommendation concerning aircraft refueling.

##  S.1.2.3. Value of the Smallest Unit for Aviation Turbine Fuel

**Source:** Veeder-Root

**Background/Discussion:** At the NCWM Annual Meeting in July, the VTM
code Section 331-1, S.1.1.3. Value of Smallest Increment was changed to
make the smallest increment 1 gal for aviation jet fuel metering. This
item is a follow-on to that item for recognizing the normal
installations and operations of the aviation industry for jet fuel. The
aviation industry meters and registers jet fuel in whole gallons in
fixed applications as it does on aviation refueling vehicles (VTM code).
Jet fuel consumers normally expect whole gallon increments.

In most applications, 2 in or larger (150 gal/min or greater) PD meters
are used. Retail sale of jet fuel from a fixed fueling system is done in
the industry, and there are self-serve jet aviation installations. The
minimum flow rate of 150 gal/min relates to a 2 in meter that is not
mounted in a dispenser housing. If "self-contained" dispensers were
available and used for jet fuel, it would use a smaller meter with less
flow rate and the expected minimum increment would be 0.1 gal.

The "exemption" requested for jet fuel is not for "dispensers," but for
2 in and above meters.

See agenda Item 4.

**Recommendation:** The Sector reviewed the following proposal for
possible forwarding to the NCWM S&T Committee for consideration.

**Proposal:** Modify Handbook 44, Section 3.30., paragraph S.1.2.3.
Value of the 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 pt) on retail devices;

(b) 5 L (1 gal) on wholesale devices.

> **[(c) 5 L (1 gal) on meters with a rated maximum flow rate of 575 L
> (150 gal/min) or more used for aviation turbine fuels.]{.underline}**
>
> This requirement does not apply to manually operated devices equipped
> with stops or stroke-limiting means.
>
> (Amended 1983, 1986, and 200X)

**Conclusion:** The Sector discussed the Veeder-Root proposal to add an
exemption for jet aircraft refueling to S.1.2.3. to allow the smallest
unit required to be 1 gal on meters with flow rates of 575 L
(150 gal/min) or more. One member noted that the similar exemption to
the requirements in the VTM Code lists the flow rate as 375 L
(100 gal/min) and suggested that the flow rate be the same in both
codes. The Sector agreed and modified the proposal 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 pt~~ [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}.**

(c) **[5 L (1 gal) on meters with a rated maximum flow rate of 375 L
    (100 gal/min) or more used for jet fuel aviation refueling
    systems.]{.underline}**

The Sector agreed to forward the modified proposal to the SWMA and NCWM
S&T Committees for consideration.

##  Testing Meters Made of Different Metals

**Source:** California NTEP Laboratory

**Discussion/Background:** The California NTEP Laboratory is conducting
an NTEP evaluation of a family of meters using multiple products in
different product families. The meter family includes meters made of
aluminum and stainless steel. Because Publication 14 does not
specifically address this scenario, the laboratory is asking for input
from the Sector before testing starts.

**Recommendation:** The Sector discussed the scenario described above.
The following proposal was offered as a possible solution. The Sector
reviewed the proposal for possible forwarding to the NTEP Committee for
inclusion in Publication 14.

**Proposal:** Add a new Section F. to the Publication 14 Technical
Policy as follows and renumber subsequent sections:

**[U.]{.underline} [Meters Within the Same Family Made of Different
Materials]{.underline}**

**[When multiple meters within a meter family, made of different
materials, are submitted for evaluation, all meters will be tested with
at least one product from each product family to be included on the CC
and at least one meter will be tested with the range of products
required in the product family table for the meter type (e.g., positive
displacement, turbine, mass meter, etc.) submitted for
evaluation.]{.underline}**

The MMA provided the following white paper for Sector consideration
during the discussion:

> **Meter Manufacturers Association**
>
> Speaking as experienced manufacturers of PD Meters, Turbine Meters,
> and Mass Meters; it is our experience that the materials of
> construction do not affect the quality of measurement over the
> specified operating range of a particular metering technology, as
> these have been considered and accounted for during the design phase
> of the meter.
>
> ***It is the manufacturers responsibility to ensure that the meter
> meets type***, additionally material selection is the manufacturer's
> responsibility and is typically driven by the requirements of chemical
> compatibility with the liquid products that are being measured or by
> industry regulations. (i.e., non ferrous meters for aircraft
> refueling).
>
> Materials are not selected or modified for reasons of accuracy. The
> market does identify and eliminate the inferior products through the
> normal surveillance process as well as the manufacturers' warranty

>
> It is normal industry practice to include material varieties such as
> Stainless Steel, Aluminum, cast Iron, Plastic, etc. into one meter,
> for example some of our PD meters have cast steel outer housings,
> stainless steel bearings, cast iron rotors, anodized aluminum blades
> or cast Iron blades or Plastic blades. Non-ferrous aircraft meters
> will utilize aluminum cast components and Stainless Steel bearings. We
> manufacturer turbine meters with stainless steel housings and aluminum
> rotors, the point being the measurement accuracy is a function of the
> manufacturing process, not the materials used.
>
> [It is not the intent of Handbook 44 to differentiate between
> measurement technologies]{.underline}, only the intended application.
>
> Doesn't material selection fall under measurement technology?
>
> ***Where do you draw the line on NTEP lab decisions on the materials

>
> The manufacturers believe that the answer to the question is in the
> **[LONG]{.underline}** history of meters themselves. There are
> hundreds of thousands of meters in service in the United States used
> for direct sales (i.e., home heating oil delivery, loading rack
> wholesale deliveries, aircraft refueling, agriculture chemical
> deliveries, etc.). These meters are verified routinely by the local
> Weights and Measures agencies, if problems are detected (accuracy out
> of range) then they are taken out of service.
>
> **Summary:**
>
> The meter manufacturers make determination of materials of
> construction.
>
> Meter manufacturers make the determination of what particular
> attributes of a meter enable it to be considered as "part of a
> family."
>
> **[Questions that need to be answered in order to make an informed
> decision:]{.underline}**

1.  Is there a real world problem that requires a solution by the
    inclusion of a new section specifically aimed at materials in
    Publication 14?

2.  Is there an inequity in the market, facilitation of fraud?

One of the NTEP laboratories stated that during an evaluation of a mass
flow meter, the performance was different for two meters with different
"tube" materials. Two mass flow meter manufacturers stated that if both
meters were calibrated for the product being measured, there should be
no difference in performance due to "tube" material. Another laboratory
stated that the permanence test of a meter conducted after 30 days is
not a true indicator of long‑term permanence. Another member stated that
NTEP should be interested in testing key characteristics and
metrologically significant components.

**Conclusion:** The Sector agreed that the best approach for resolving
the issue of what components are "metrologically significant" and
require additional evaluation, was to include the discussion and
development of a proposal for Sector consideration in the tasks of the
WG formed to develop a new Product Families table approach, as discussed
in agenda Item 5.

# Additional Items Added at the Meeting

##  Number of Tests Required for Permanence Test

**Source:** Endress & Hauser Flowtec AG

**Background/Discussion:** An application was submitted for evaluation
of mass flow meter. During the initial test, not only was the meter
tested and met all requirements for the 10 to 1 turndown ratio, but it
also passed at 12 to 1 turndown ratio. Following the required time and
throughput, the permanence testing was conducted. The meter passed
testing for the 10 to 1 turndown ratio but failed at the 12 to 1 ratio.
The question was: Should a CC be issued for the meter limited to only a
10 to 1 turndown ratio or should the device fail and testing begin over?

**Conclusion:** The Sector discussed the issue at length and agreed that
the device should have a CC issued for the required 10 to 1 turndown
ratio. During the meeting, the Sector proposed changes to Publication 14
as shown below to clarify how this situation should be addressed if it
happened again in the future. The Sector agreed to forward its
recommendations to the NTEP Committee for consideration at the 2007 NCWM
Interim Meeting.

Permanence Test Procedures for Meters

A. Field Evaluation and Permanence Test of New-Design Meters in Retail
Motor-fuel Dispensers

All new-design meters are subject to a permanence test. If a meter is
the same as one in a previously tested dispenser, a permanence test is
not required. NTEP reserves the right to require a permanence test based
on the result of the initial examination.

Initial Examination

1\. All meters of the new type \-\-\-\-\-\-\-\-\-\-\-\-\-\--

2\. At least one meter \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

3\. All meters must
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

4\. Repeatability - When consecutive \-\-\-\-\-\--

Subsequent Examination

1\. Following the period of use, the tests listed above are to be
repeated. All results within the range of flow rates to be included on
the CC must be within the ~~acceptance~~ [applicable]{.underline}
tolerances. [Extended flow range testing performed at the manufacturer's
discretion may be included on the CC provided the results are within the

##  Permanence Tests for RMFD

**Source:** Gilbarco

**Background/Discussion:** During a recent evaluation the measuring
element from a device with an existing CC was installed in a new frame.
For the permanence test, the evaluator required a throughput of
20 000 gal and a minimum of 20 days use before conducting the follow-up
tests. The manufacturer believes that the permanence criteria for RMFDs
in Publication 14 should be separated into a 20-day requirement for
electronics and a 20 000 gal throughput for metering elements. The Meter
Manufacturers Association (MMA) developed a proposal to modify
Publication 14 to distinguish between electronics and measuring elements
and between elements covered by an existing CC and new equipment being
evaluated for the first time.

**Conclusion:** The Sector reviewed the MMA's proposed changes and
agreed to forward them to the NTEP Committee with the recommendation
that they be approved as revisions to the 2007 edition of
Publication 14.

A. Field Evaluation and Permanence Test of New-Design Meters in Retail
Motor-fuel Dispensers

All new-design meters are subject to a permanence test. If a meter is
the same as one in a previously tested dispenser, a permanence test is
not required. NTEP reserves the right to require a permanence test based
on the result of the initial examination.

Initial Examination

1\. All meters of the new type
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

2\. At least one meter
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

3\. All meters must
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

4\. Repeatability - When consecutive \-\-\-\-\-\-\-\-\-\-\-\-\-\--

Subsequent Examination

1\. All meters of the new type installed at the type evaluation location
must perform within acceptance tolerance throughout the time and volume
period specified below.

2\. ~~The examination will be conducted no sooner than 20 days after the
initial examination and not before the previously chosen meters have
measured at least 20 000 gallons for throughput testing.~~

> [The examination will be conducted as applicable:]{.underline}

-   [No sooner than 20 days for electronic changes of metrological
    significance.]{.underline}

-   [20 000 gal for throughput testing for mechanical changes of
    metrological significance.]{.underline}

3\. Five tests
\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\--

4\. Repeatability - When consecutive \-\-\-\-\-\-\-\-\-\-\-\-\-\--

B. Field Evaluation Test of Previously Evaluated
[Components]{.underline} Retail Motor-Fuel Dispensers ~~Using Different
Previously Evaluated Meters~~

**[Different Previously Evaluated Meter]{.underline}**

Previously evaluated dispensers using a previously type evaluated meter
and indicator (register) will be subject to an initial test. Based on
the test results of the initial test, NTEP may require a permanence
test.

**[Nonmetrological Changes]{.underline}**

[An administrative review shall be conducted to issue a new CC or revise
an existing CC for previously evaluated devices because of non
metrological changes. Based on the results of the administrative review,
NTEP may require an initial test.]{.underline}
