2Overview
The Dresser Model 6 Prover is an integrated computer-controlled system designed for shop or field
proving of rotary, turbine, and diaphragm-type positive displacement gas meters. This Prover is designed
for transfer proving using only air as the test medium. Electric blowers mounted on a manifold or a skid
provide the test air flow (vacuum).
This Prover system consists of the following major components:
•Master Meter(s) as the measurement reference standard
•Pressure transducers and temperature probes
•Blowers
•Prover Hose(s)
•Electronic cables and accessories with a storage case
•Junction Box
•Controller Box
This Prover also has the unique capability to test Dresser NGS meters equipped with the Integral Micro
Corrector (IMCW2) and other Dresser NGS electronics, such as the ETC and ES3 Electronic Temperature
Compensating Devices.
The Model 6 Prover is a portable unit that can be transported into the field for on-site testing. Because
the Prover is a precision instrument, transport it with care and ensure that it is properly secured and
covered for protection from moisture and dirt.
This unit is designed for indoor and outdoor usage, but it is not designed for use in rain conditions. The
ambient operating temperature is from +32°F to 140°F. Maximum altitude is 6,500 feet above sea level
with an environment of pollution degree 2.

Dresser™ Model 6 Transfer Prover Operation and Maintenance Manual for 2/10M and 10M Versions

2.1 Operating Principle
The Prover operates as a transfer test. Blowers are used to pull a vacuum, which draws ambient air into
the meter under test (MUT or Field Meter) and through a connecting hose directly into the Master Meter.
The Field Meter registers pressure, temperature, and volume that are compared to the values registered
by a Master Meter on the Prover. The Master Meter is a Reference Meter with known performance
characteristics that are traceable to national and international standards.
In the normal test set up, the mass of air passes through the Field Meter and then through the Master
Meter. Since the Master Meter’s characteristics are known, the meter under test can be characterized
based on the difference in its performance parameters as compared to the Master Meter. The difference
in performance is expressed in terms of accuracy. Proof and percent error are also displayed.
2.2 Software
Prover software is available for setting test configurations, performing calculations, and presenting the
Prover’s flow test data. The software stores predetermined Field Meter test configurations and allows
custom configurations to be created. It performs all calculations at the end of each test run and displays
the pressure and temperature readings, Field Meter proof, Field Meter accuracy, and percent error. Test
reports can be saved in different formats and downloaded. The software can be configured for Imperial or
Metric display and storage of data.
The software is accessed through a web browser and a connection to the Prover. The connection can be
wireless or through a Cat5e or Cat6 shielded Ethernet cable connected to the Prover. Any device with a
web browser and the ability to connect with the Prover, such as a laptop, desktop, tablet, or cell phone
can be used. No software needs to be installed on the connecting device. The device connects wirelessly
with a router on the Prover, so no Internet service is needed.

due to the positioning of the Field Meter temperature probe. Avoid leakage at or around the P&T
Adapter or Field Meter temperature probe.
S’assurer que la sonde thermique du débitmètre ou l’appareil mis à l’essai ne peut pas être
endommagé en raison de la position de la sonde de température. Éviter toute fuite de, ou autour
de, l’adaptateur ou de la sonde de température P&T.
10. Plug the end of the Field Meter temperature probe cable into the Field Meter Junction Box
connection labeled TEMP PROBE.
11. Ensure the pressure lines are properly connected from the P&T Adapter (the T-shaped brass piece) at
the silver quick-disconnect fitting to the Field Meter Junction Box:
•One end of a blue inlet pressure line connects into the P&T Adapter and the other end connects
to the port labeled IN PRESSURE on the Field Meter Junction Box.
•One end of a black outlet pressure line connects into the Pressure Adapter, and the other end
connects to the port labeled OUT PRESSURE on the Field Meter Junction Box.

Note: Use an ID Pulser to test only non-compensated (non-TC) rotary meters.
Figure 14: Instrument Drive Pulser test setup
As the drive dog travels around the interior hole of the adapter plate during testing, it is critical that
continuous contact is maintained between the drive dog and the follow pin before securing the ID
Pulser to the adapter plate:

CAUTION
Improper alignment and engagement of the instrument drive dog can lead to equipment damage.
Un mauvais alignement et l’engagement du toc d’entraînement peut endommager l’instrument.
a. Place the ID Pulser over the center hole of the adapter plate. Determine which set of mounting
holes in the adapter plate to use to get the ID Pulser shaft most closely centered over the adapter
plate and drive dog.
b. Fasten the ID Pulser to the adapter plate. This can be done by using the two (2) mounting clamps
provided.
You may need to make fine adjustments to the position of the ID Pulser when the meter test
begins, so do not tighten the mounting clamps all the way down yet.
c. Plug the ID cable into the Field Meter Junction Box at the connection labeled VOLUME INPUT.
13. If using an Optical Scanner as the test equipment, perform this step.

Note: Mounting the Optical Scanner and positioning the lens relative to the target is
critical for the reliable operation of the device.
a. Align the Optical Scanner as indicated in Table 4 and hand tighten. For illustrations of the test
wheel and dials, refer to Figure 17 and Figure 18.
For Series A1, refer to Figure 19. For Series B2, refer to Figure 20. For series B3, refer to Figure 16.
For correct focusing and positioning, refer to steps c and d.

Note: The distance X shown in Figure 19 and Figure 20 should be approximately 1/2 inch
(or about the width of your small finger). Set angle A slightly off-center at approximately
15 degrees.
