Field Evaluation and Permanence Tests for Metering Systems

(Section C. below is part of agenda item E.)

C. Field Evaluation and Permanence Test for Vehicle-Tank Meters, Except
LPG, Cryogenic, and CO~2~

The following tests are considered to be appropriate for vehicle-tank
metering systems:

-   Four test drafts at each of five flow rates.

-   One vapor or air eliminator (product depletion) test.

Note: The normal test of a measuring system shall be made at the maximum
discharge rate that may be anticipated under the conditions of the
installation. Any additional tests conducted at flow rates down to and
including one-half of the sum of the maximum discharge flow rate and the
rated minimum discharge flow rate shall be considered normal tests.
(Code reference N.4.1.)

Only one meter is required for the initial test, and after the test, the
meter will be placed into service for the permanence test. The minimum
throughput criterion for these meters is the maximum rated flow in units
per minute x 2000.

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
certificate of conformance must be within the applicable tolerances.
Extended flow range testing performed at the manufacturer\'s discretion
may be included on the certificate of conformance provided the results
are within the acceptable tolerances.

Tests of Automatic Temperature Compensating Systems (Code
Reference T.2.1.)

> **[The difference between the meter error (expressed as a percentage)
> for results determined with and without the automatic
> temperature-compensating system activated shall not
> exceed:]{.underline}**
>
> **[(a) 0.4 % for mechanical automatic temperature-compensating
> systems; and]{.underline}**
>
> **[(b) 0.2 % for electronic automatic temperature-compensating
> systems.]{.underline}**
>
> **[The delivered quantities for each test shall be approximately the
> same size. The results of each test shall be within the applicable
> acceptance or maintenance tolerance.]{.underline}**

[Repeatability on Vehicle-Tank Meters (Code
Reference T. 3.)]{.underline}

> **[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.]{.underline}**
>
> **[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

# Carryover Items

## Table of Key Characteristics of Products in Family Products Table for Meters

**Source:** NTEP Director

**Background:** Prior to the 2006 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 Family 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 locate various tables and charts to help ID
> 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 and CentiStokes.
>
> 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 but no temperatures. While S.G. may not be as
> temperature-dependent, some reference should still be cited.
>
> To expand on this in the table in Pub 14 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 consider 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 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 seem 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.

At the 2006 meeting, the Sector discussed the NTEP director's concerns
and explored the concept of having a table of additional product
characteristics beyond what is currently in the Product Family Table.
The Sector considered appointing a separate work group to develop this
item for presentation and discussion at the next meeting. The Sector
ultimately agreed that further development of key characteristics should
be included in the tasks of the work group formed to develop a new
Product Family Table approach, as discussed in the 2006 agenda Item 5.

**Work Group (WG) Recommendation:** The Product Family Table from Pub 14
has been reviewed and reorganized by the work group as shown below. The
new table removes the named liquids and focuses on the influence factors
for the mass, magnetic, positive displacement, and turbine flowmeters.

There remains a need to list the liquids describing the viscosity,
specific gravity, and conductance.

**Discussion/Conclusion:** The WG presented their work to date and
received comments and recommendations. One member stated his belief that
the statement in the table that the Compressed Liquids Family was not
applicable to positive displacement meters should be removed. If a
manufacturer is able to produce a positive displacement meter that will
measure compressed liquids appropriately, they should not be restricted
from doing so. The WG will continue to develop the item for presentation
and discussion at the next meeting. The WG will also look at identifying
the units of measure and reference temperatures as appropriate for
various products in the table.

## NTEP Checklist for Water Meters in Submetering Applications

**Source:** NTEP Director

**Background/Discussion:** The NTEP Committee asked the MS to consider
and develop a checklist for residential water meters. These devices will
most likely be used for submetering. 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:

I have found a Word version of the water meter checklist and test
procedure and copied the specific section. This is used as an EPO for
field enforcement, but the same guidelines are followed in type
approval. Three tests at three flow rates are performed and
repeatability is verified. The basic form can be printed and used for
water meter tests. This follows HB 44 sections 1.10. and 3.36.

In type evaluation California uses a procedure (not a checklist) for the
evaluator, which starts with an application review and other directives
not pertinent to actual testing. An electronic form is available which
is specific for the California provers. California follows the testing
criteria of the EPO. The electronic form could probably be formatted to
the Pub 14 format.

The California type evaluation checklist for Domestic Cold Water Meters
was included as Appendix C of the 2006 meeting agenda.

At its 2006 meeting, 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.

At the time of development of the 2007 meeting agenda no information had
been received from the WG. Following distribution of the initial agenda
the California NTEP Laboratory submitted a draft checklist based on
Handbook 44 that is used in their lab. The Sector reviewed the draft
checklist to determine if it should be submitted to the NTEP Committee
for inclusion in Publication 14 with or without modification as shown in
Appendix D.

**Conclusion:** The Sector reviewed the checklist submitted by the
California NTEP laboratory. The NTEP director stated that the draft
checklist needs to be formatted for inclusion in Publication 14. The
NTEP director and the California laboratory will convert the checklist
into the proper format and submit it to the members with a ballot for
approval prior to forwarding to the NTEP Committee for inclusion in
Publication 14.

## NTEP Checklist for LPG Vapor Meters in Submetering Applications

At its 2006 meeting, Sector agreed 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 in the WG.

At the time of development of the 2007 meeting agenda no information had
been received from the WG. At the meeting, the Sector reviewed a
recommendation and considered changes to Publication 14 deemed
appropriate.

**Conclusion:** After reviewing a draft presented by the California NTEP
laboratory, the Sector agreed that "LPG" in the title should be changed
to "Hydrocarbon Gas" so that the measurement of natural gas would be
included. The California NTEP laboratory and the NTEP director will
continue to develop this checklist for presentation and discussion at
the next Sector meeting.

## 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.

At the 2006 meeting 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 Made of Different Materials within the Same
Family]{.underline}**

**[When multiple meters made of different materials within a meter
family 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 manufacturer's 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 (e.g., 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 manufacturer's warranty
process.

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 SS 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 HB 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 of
construction?***

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 (e.g., home heating oil delivery, loading rack wholesale
deliveries, aircraft refueling, agriculture chemical deliveries, etc.).
These meters are verified routinely by the local W&M agencies, and 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 Pub 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.

After further discussion at the 2006 meeting, 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 Family
Product Table approach, as discussed in agenda Item 5.

**Recommendation/Discussion:** At the time of development of the 2007
meeting agenda no information had been received from the WG, nor was any
formal update presented at the meeting. One industry member suggested
the item be withdrawn. The Sector technical advisor cautioned the group
that withdrawing the item would not resolve the question as to whether
or not a change in material used in the construction of a meter would
require that the model be resubmitted for NTEP evaluation in order to
maintain a valid CC. The manufacturers present at the meeting met
following the conclusion of the first day's agenda and came back with
some suggestions for resolving the problem. One suggestion was for the
manufacturer to submit a drawing listing material used, similar to what
is done with [Underwriters Laboratories, Inc.](http://www.ul.com/) (UL),
who evaluates or tests what they consider to be the worst case. Another
suggestion was to include ASTM specifications for the original material
and any replacement material. Some of the NTEP laboratories believed
that changing material constitutes a change of design and, therefore,
requires a new model designation.

**Conclusion:** The Sector was not able to reach a consensus on this
item, and it will be carried over for further development and
consideration at the next Sector meeting.

# New Items

## Revise NTEP Policy F "New Product Applications for Meters"

**Source:** Endress and Hauser

**Background/Discussion:** Publication 14 Policy F addresses \"New
Product Applications for Meters\". Criteria 1 and Criteria 2 apply to an
initial evaluation of a device where a new product family is added.
However, when a device has been repeatedly evaluated, the entire range
of meter sizes should be covered---not just one size larger and one size
smaller.

Researching past NTETC Sector reports, Endress and Hauser found little
information regarding Policy F. One year there was a little discussion
from an unidentified lab reporting that Policy F was a necessity for
initially submitted devices. Criteria 2, which requires the new product
fall within a less strict NIST Handbook 44 accuracy class than the most
strict accuracy class covered by the existing CC, places a restriction
upon devices previously tested and held to a high level of performance.
Endress and Hauser recommended that Criteria 2 be deleted from Policy F.

The Sector was asked to consider the request to delete Criteria 2 from
Policy F and develop a recommendation to the NTEP Committee.

The NTEP laboratories discussed this item thoroughly. The California lab
submitted a proposal to reverse requirements 1 and 2 of Section F in
Publication 14. The laboratories were concerned that accuracy class
should not be the only consideration for adding a new product to a CC.
The family products subgroups and a product's physical characteristics
should also be considered when determining what products can be added to
an existing CC based on the testing of one additional product.

At the Sector meeting, Endress and Hauser explained they recently
experienced a problem with an NTEP laboratory's interpretation of
Section F during an evaluation. The Sector discussed the issue at length
and developed the chart shown below as a replacement to the current text
in Section F.

F. New Product Applications for Meters

**~~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 meter sizes will be
covered for the 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 the meters meeting the requirements of paragraph E,
Meter 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:

> a\) the results of the initial test were not questionable; and
>
> b\) multi-point calibration may not be used to add the new product.

**Conclusion:** The Sector agreed to forward the proposed changes to the
NTEP Committee for approval and inclusion in Publication 14.

## Add Testing Criteria to NTEP Policy U "Evaluating electronic indicators submitted separate from a measuring element"

**Source:** California NTEP Lab

**Background/Discussion:** Section U allows for testing an indicator
separate from a measuring element. Specific test criteria has not been
developed for this section.

**Recommendation:** Develop and add specific criteria for testing an
indicator separate from a measuring element for this section. California
recommended using Canada\'s test criteria as a guideline to develop the
tests as outlined in Appendices A, B, and C.

**Conclusion:** The Sector agreed the California NTEP laboratory should
lead a WG to develop a specific test procedure for review at the next
Sector meeting. Members of the WG are Dave Rajala (Veeder Root Company),
Rich Miller (FMC Measurement Solutions), Maurice Forkert (Tuthill
Transfer Systems), Dmitri Karimov (Liquid Controls), Rodney Cooper
(Actaris Neptune), and Ralph Richter (NIST).

# 

## Next Meeting

**Background/Discussion:** The Sector discussed the date and location
for its next meeting.

**Conclusion:** The Sector agreed that the 2008 meeting should be held
immediately prior to the Southern Weights and Measures Association
Annual Meeting that is tentatively scheduled for October 12 - 16, 2008,
at the Doubletree Hotel in Atlanta, Georgia.

# Additional Items as Time Allows

## Temperature Compensation for Liquid-Measuring Devices Code

**Source:** NCWM S&T Committee

**Background/Discussion:** The NCWM S&T Committee is considering a
proposal to modify Section 3.30. Liquid-Measuring Devices (LMD) Code by
modifying paragraphs S.2.6., S.2.7.1., S.2.7.3., N.4.1.1.(a) and (b),
N.5., UR.3.6.1.1., and UR.3.6.1.2., to add new paragraphs S.1.6.8.,
S.2.7.2., S.4.3., UR.3.6.1.3., and UR.3.6.4., and to renumber other
existing paragraphs as appropriate to recognize temperature compensation
for retail devices as shown in Item 330‑4 of the Final Report of the
2007 S&T Committee:

Prior to the 2007 NCWM Interim Meeting, the Committee recognized via
reports from the regional L&R committees and other sources that there
was increasing support within the weights and measures community to
address temperature compensation features for the retail sale of
petroleum products in the Liquid-Measuring Devices Code. In response to
these concerns and to encourage uniformity in applications where
temperature compensation is being used, the Committee developed this
proposal to provide design and performance requirements and testing
criteria for retail metering systems that incorporate temperature
compensation capability. The Committee was also concerned that if the
current L&R Committee's proposed language for the Method of Sale of
Commodities in NIST HB 130 was adopted, retail motor-fuel devices could
be placed in service with no guidelines in NIST HB 44 for type approval
and field testing. The L&R proposed language would permit the
temperature-compensated sale of petroleum products at all levels of
distribution.

At the Interim Meeting, the L&R Committee moved forward with a Method of
Sale proposal containing permissive language for retail sales of
petroleum products using automatic temperature compensation (see L&R
Item 232‑1). Although the Committee recognized that this S&T item was
still not fully developed, it felt it could resolve the remaining issues
in time for the NCWM Annual Meeting in July 2007; therefore, the
Committee unanimously voted to make this item a "priority" Voting item
as described in Section H of the Introduction of HB 44. The Committee
felt strongly that if the L&R item passed it was very important there be
a corresponding S&T item that provided HB 44 guidance as described
above. Following the Committee vote, the Committee chairman went before
the NCWM Board of Directors (BOD) for their input. The BOD instructed
the Committee to make this an Information item. Irrespective of the
concerns about the timing of adoption of language in HB 130, after
further deliberation the Committee concurred with the BOD and added the
proposal to its agenda as an Information item. The BOD further informed
the Committee of its plan to form a steering committee to provide
guidance and give support to both the S&T and L&R Committees on
temperature compensation issues. The Committee looks forward to working
with the steering committee on this important issue.

This item is still in development. Below are some of the issues the
Committee is currently working on.

> **Recorded Representations (S.1.6.7.):** What, if any, abbreviations
> are acceptable for devices equipped with ATC (e.g., gal at 60 ºF)?
>
> **API Gravity:** How should the API gravity be entered in the device
> and what API gravity should the inspector use during test? Should an
> average API gravity be used (national or state)? The Committee will
> work on gathering API data in order to resolve this issue.
>
> **Difference between Net and Gross (T.4.):** Is the current tolerance
> of 0.1 % (electronic) appropriate for field-testing of retail devices
> with ATC? Will maintaining our current tolerances mean taking extra
> drafts to obtain a stable temperature? The Committee will gather data
> concerning temperature measurement.

The Committee will continue work on this item and will seek input from
the regions and other interested parties in the weights and measures
community.

**Background/Discussion:** The Sector was asked, if time allowed, to
review the proposed changes to the LMD code and provide comments and
recommend changes to the NCWM S&T Committee.

**Conclusion:** The Sector did not have time to review this item during
the meeting.
