Large Meter Evaluation and Maintenance

The Large Meter Evaluation and Maintenance program is designed to help a Utility retrieve and retain the large amounts of potential revenue associated with master (production), industrial, and commercial meters.  The program, as designed by M.E. Simpson Co., Inc., includes water meter testing, meter repair, and post-testing when necessary.  Following is a description of the individual phases: 

METER EVALUATION

Large Meter Evaluation is designed to locate inconsistencies within the water meter reading and billing cycles and to identify meter accuracy problems resulting from improper sizing and application.  The evaluation will allow the development of a cost-effective meter test and meter repair or replacement schedule for the large meters and provide recommendations for the correction of the problems discovered.

METER TESTING

1 1/2" and larger meters will be tested at flow rates in accordance with AWWA standards. Testing is done by comparative methods using a certified test meter or a pitot rod (high flow) to test the meter within its normal operating range.  Our comparative test meters, from Sensus, record both total volume and current velocity with electronic registers which are automatically reset to zero after each of the 3 to 6 tests conducted. 

Master Meters will be tested in accordance with AWWA standards. Using an “in-line” pitot rod the master meter can be tested at a single flow or over a broad range of flows.  M.E. Simpson Co., Inc. manufactures and uses the Polcon^® Pitot Rod along with the Polcon^® Sentry electronic flow recorder

METER REPAIR

• Meters that are found to be stopped, broken, or inaccurate will be repaired by M.E. Simpson Co., Inc. and calibrated back to AWWA standards. 
• Major parts such as chambers, turbine assemblies, check valves, and registers are replaced at extra cost.
