Clark’s CSLFC liquid ultrasonic flow transmitter has no element in the fluid stream to add pressure loss, no moving parts and no hysteresis. Its output is unaffected by changes in fluid temperature, density and viscosity. Using the “sing around” method, the transducer alternates between transmitting and receiving to measure differences in flight time between upstream and downstream transmissions. A sound pulse is transmitted from an upstream transducer toward a downstream transducer. The received sound pulse then triggers a second downstream transmission that then triggers a third and so on for a specific number of cycles.
