Case Study

3/4-Inch MMPD Flow Meter Accuracy And Endurance Testing

Source: Master Meter, Inc.

Utah State University was contracted by Master Meter to perform flow calibrations at the Utah Water Research Laboratory (UWRL) in Logan, Utah on five 3/4-inch MMPD (Master Meter Positive Displacement) flow meters. The testing required that the new meters be base line tested in cold water (water less than 80 degrees Fahrenheit) and then operated at a set flow rate of 15 gallons per minute until incremental volumes of 1,000,000 gallons, 2,000,000 gallons, and 3,000,000 gallons had passed through each meter. Upon reaching the volumes indicated, the meters were then accuracy tested to identify any shifts in performance associated with throughput. This test report summarizes the testing completed to date. As future data are collected, this test report will be updated.
