Emerson Therm-O-Disc’s Water Flow Sensor (model 80FS) allows cooling units to measure and communicate system capacity by continually monitoring both temperature and flow velocity of water. The sensor utilizes technology that enables consistent measurement close to elbows as near as three pipe diameters. Unique algorithms enable the same sensor configuration to serve multiple pipe sizes ranging from 1” to 4”. Product options include NPT or brazed-pipe connections, analog or digital outputs, several supply voltages of 12 VDC or 24 VDC and flow ranges up to 200 gpm.
