The Small Meter Test System developed by MARS Company employs the latest in design and process control technology, setting the worldwide standard for the small meter testing and management industry. This versatile system can be configured to meet the testing needs of virtually any small meter management organization.

MARS Test Bench Systems are designed to meet / exceed American Water Works Association (AWWA) recommendations, National Institute for Standards and Technology (NIST) Handbook 44 Specifications, ISO Specifications and other standards and requirements.

Revenue Recovery

Understanding how your meters perform in the field will allow you to reduce unaccounted for water in your system.

Increase Confidence

Designed to operate using Volumetric or Gravimetric (optional) technology and to meet/exceed AWWA, ISO and NIST specifications.

Simplify Operations

Automation is available with optional Gravimetric and MARS M3 Meter Management Software integrations.

Typical Applications

Water utilities or water meter manufacturers requiring the testing of meters from 5/8” to 2” sizes (larger sizes available)

Tests meters of all lengths and types

Where testing to a higher standard of accuracy and repeatability is required

Where improvements to revenue, manpower utilization, efficiency, and safety are needed

In retrofits and additions where existing test equipment alone is no longer able to meet the needs of the utility or manufacturer

Where software and controls only are needed to be retrofitted into already existing sufficiently operational testing equipment

Standard and Optional Features

Available on every Small Meter Test Bench System configuration.
* Denotes Optional Items, contact MARS for details

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

Optional larger sizes, including 300 Gal., 500 Gal., and others are available.

Two (2) precision rotameters that cover a flow range from .1 – 60 GPM (optional third rotameter up to 160 GPM if high flow on 2” meters are specified).

Corrosive Protection (polyester coated steel bench frame).

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

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.

Learn More about MARS M3 Enterprise Software

With the introduction of ultrasonic and electromagnetic meters under ANSI/AWWA C715-18, additional test requirements were introduced. 

MARS has incorporated many of these into Small Meter Test Bench Systems as an optional upgrade to new and existing equipment.

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.

Learn More about MARS Recirculation Systems

  • Utilizes municipal (public) service to supply the needed water to the test system
  • The water is drained from the measurement tank and then directed to the storm drain, municipal sewer, or wherever the user sees fit
  • The water service must be able to provide a pre-determined flow at a specific pressure (requirement depends on bench size and specifications) in order to achieve proper test results
  • Not recommended in situations where the cost of water is high or water conservation is desired

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.
