Mobile Meter Test Systems
The Truck, Van or Trailer-Mounted Test System is designed to fit on a utility vehicle, pickup truck, van or on/in a trailer, supplied by the customer (unless specified). The test unit is based on comparison meter technology and is fully linearized and calibrated to avoid inherent test meter accuracy curves, providing clients with the ability to test meters in the field without removing them from service.
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.
Understanding how your meters perform in the field will allow you to reduce unaccounted for water in your system.
Designed to operate using Volumetric technology and to meet/exceed AWWAand NIST specifications.
Automation is available with MARS M3 Meter Management Software integrations.
Standard and Optional Features
Available on every Mobile Meter Test System configuration.
* Denotes Optional Items, contact MARS for details
Comparison meters are precision high accuracy turbine type meters. Meters to be installed in pipe manifold with correct up-stream and down-stream straight pipe in accordance with manufacturers specifications.
Corrosive Protection (polyester coated steel bench frame).
Supplemental Hardware, such as hoses or a MARS ThrustBuster, can be ordered along with a MARS Mobile Test System
MARS M3 Meter Management Software is required to operate MARS Mobile Test Systems.
This includes control over all line select valves and metering devices while providing data entry and collection using a controlled process.
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.
