Singer Valve’s battery operated single point insertion, electromagnetic flowmeter measures flow rate when power is not available. The sensor comes precalibrated from McCrometer’s NIST traceable calibration lab and requires no calibration in the field. It can be installed on either side of a Singer valve on the inlet connection and only requires three pipe diameters’ clearance upstream. It is available for valve sizes from 3 to 36 inches and can be installed with any pilot system. With no moving parts and a single-piece design, the sensor contains nothing to wear or break and is mostly immune to clogging by sand, grit or debris. 888/764-7858; www.singervalve.com.
