ClarkSonic Ultrasonic Flow Transmitters can be used for measuring flow in most clean liquids and many liquids with entrained solids. Applications include monitoring flow rates of chilled or heated water as part of a green technology program as well as in municipal, process, and industrial systems. Model CSLFC is designed for flows to 400 gallons per minute (gpm) in 3/4- to 3-inch pipe, and Model CSLFB is designed for flows to 3,000 gpm in 4- to 10-inch pipe. ClarkSonic transmitters utilize the “sing around” method, where the ultrasonic transducer alternates between transmitting and receiving to measure differences in flight time between upstream and downstream transmissions. According to the manufacturer, the primary advantage of this method is that the velocity of the fluid is being measured independent of the relative speed of sound in that given fluid. The output of ClarkSonic transmitters is also unaffected by changes in fluid temperature, density, and viscosity.
