Description:
Electromagnetic flowmeters that conform to the guidelines described in this document can be used to measure the volumetric flowrate of all liquids and sludges normally encountered in wastewater treatment plants, provided that adequate inspection and maintenance are performed as recommended to contend with potential deposits and other effects of the harsh fluids. Electromagnetic flowmeters should be accurate to the lesser of 1 percent of full-scale or 3 percent of actual flowrate. These flowmeters are not necessarily immune to the effects of approach velocity distribution. Upon installation, electromagnetic flowmeters should be hydraulically tested, by a method equivalent to that described, to provide an acceptance test and/or initial calibration.
