Keeping Meters On Line: Accurately Measuring Drinking Water and Sewage   Water Engineering & Management September 2002   Rodney Johnson
Detroit Water & Sewerage Department (DWSD) has a high stake in keeping its flowmeters up and running with calibrated accuracy. This is especially true for its 278 wholesale water meters used in its vast network of distribution lines that serve 126 communities. It also is true for metering sewage inputs from wholesale customers for its Wastewater Treatment Plant. This article focuses on a unique answer that DWSD found for keeping its magnetic meters online by means of a portable electronic system that verifies and certifies calibration, all done in-line.
