MARS Series 100 Test Bench System

The MARS Company Series 100 Meter Test Bench System makes testing water meters ½” to 2” affordable for meter shops of all sizes. 

This compact, one-of-a-kind design integrates the famously-rugged MARS fabricated frame into a reduced footprint, while providing this industry unique capability of testing meters up to two inch in size. All this, without the need for electrical or pneumatic supply for extreme portability and affordability. 

The Series 100 uses the effortless self-locking mechanism for operation, three commercial rotameters, and a patented MARS duplex 10/100 gallon stainless steel tank. Operators may accurately test at flow rates from 0.1 to 150 GPM (optional Ultra Low Flow available) with instant visual test results that require no calculations. 

With the Series 100 Meter Test Bench System, MARS Company is making meter accuracy and revenue recovery a reality for every utility.

Available Exclusively at Pollardwater.

Standard and Optional Features

Available on every configuration of MARS Series 100 Test Bench.
* Denotes Optional Items, contact MARS for details.

Test Tanks

10 Gal./1 Cu.Ft. and 100 Gal./10 Cu.Ft. Stainless Steel Duplex Tank

Flowrate Registration

Two (2) precision rotameters that cover a flow range from .1 – 60 GPM (optional third rotameter up to 150 GPM if high flow on 2” meters are specified).

Corrosive Protection

Corrosive Protection (polyester coated steel bench frame).

Supplies and Adapters

All meter adapters, meter and adapter gaskets, manual flow control valves, document station, electric actuated clamping device, carrier bars and spacer spools.

Recirculation System*

The Recirculation System recycles the test water used on the MARS Test Bench, maintaining volume and pressure to test the meters at the recommended AWWA Specifications, per Table 5-3 of the current AWWA M6 Manual.  

Benefits include but are not limited to: compliance with local, state and/or Federal laws and regulations as it reduces the chemicals released into the environment; an immediate reduction in consumption and water dumped to waste after each test; Improved customer perception as the Water District sets an example for water conservation practices.

Dual Stage Low/High Flow Automated Shutdown*

The MUN-200 is an automated shutdown feature, which provides a consistent shut off for each and every test. This provides a more accurate test and further eliminates the element of human error. 

In addition, the MUN-200 prevents accidental overflow as well, which is specified in the AWWA’s M-6 Manual as a recommended safety element.

Gravimetric Control and Automation with M3*

The MARS Company Gravimetric System includes a scale, console, computer, printer, display and the MARS M3 Meter Management Software. 

The Test Bench, with the Gravimetric System, is traceable to NIST (National Institute for Standards and Technology) Handbook 44 specifications, providing 1/10% repeatable accuracy.

MARS Calibration Certification*

With MARS Certified, you can protect both MARS and selected third-party equipment with technical assistance, software upgrades, preventative maintenance, spares management and on-site maintenance. 

Not only is the equipment upkeep essential, but ensuring all operators are fully trained on meter testing practices and procedures is critical.
