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.

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.
3Receiving, Handling, and Storage
Follow the steps and recommendations in this section to ensure your Prover and its accessories are ready
for use.
3.1 At Time of Delivery
Perform the following steps when you receive your shipment:
1. Check the packing list to verify all items have been received.
2. Inspect each item for damage and if necessary:
a. Record any visible damage or shortages on the delivery record.
b. File a claim with the carrier.
c. Immediately notify your Dresser prover supplier.

CAUTION
Do not accept any shipment with evidence of mishandling without making an immediate inspection
for damage prior to signing the carrier’s delivery record. Do not attempt repairs or adjustments, as
doing so may be a basis for voiding all claims for warranty or insurance claim with carrier.
Refuser toute expédition présentant des signes de mauvaise manipulation sans faire une inspection
immédiate des dommages avant de signer le bon de livraison du transporteur. Ne tenter aucune
réparation ou aucun réglage; le faire peut constituer un motif suffisant pour annuler toutes les
demandes de garantie ou de réclamation d’assurance auprès du transporteur.
3.2 Storage
If the product is not tested or installed soon after it is received, store it in a dry location in the original
shipping container for protection with the Prover’s operating conditions:
•Temperature range of 32°F to 140°F (0°C to 60°C)
•Maximum altitude of 6,500 feet above sea level
•Environment pollution degree 2
4Parts Identification
The following is a list and physical description of the items available for the Dresser Model 6 Prover. Your
