A municipal water district in the Southwest U.S. provides drinking water and wastewater treatment to a large distribution area.It currently serves the daily water needs of over 1.6 million people with a treatment capacity of 550 MGD.The district had been using a different measurement technology supplied by a competitor as a basis for billing their customers.It was installed on their outbound transmission line. The district had questioned for some time, the accuracy of the readingsand, after testing, they found that the billing amounts were too low. 
The water district wanted a flowmeter that was accurate, needed minimal maintenance, and did not require direct power to the unit. The remote vault where the flowmeter was to be located was susceptible to flooding, and there was no sump pump available inside the vault that contained the 8-inch pipeline. The flowmeter needed to withstand submersion.

The local Siemens sales representative suggested the water district install a Siemens SITRANS FM 8000 battery- operated magmeter to replace the older competitive unit on the 8-inch pipeline. The Mag 8000 instrument is a higher accuracy flowmeter that requires no maintenance and no power connection. It can be totally submerged with no effect on its operation. After installation, the district found the actual outbound flowrates to be much higher than the older unit was recording.
