Omega Engineering”s FDT100 ultrasonic flowmeters employ advanced transit-time technology in which two flow sensors alternately transmit and receive a signal and time of flight is used to measure flowrate. Designed for long, economical service in either consumable or industrial water applications, the battery-powered meters have no moving parts. Pressure loss is minimal and filtration unnecessary. Long-term stability and a wide measurement range facilitate monitoring of consumption and leakage. Both flange styles — 150 lb. ANSI and DIN — come in various sizes, with a choice of integral or remote electronics that display flowrate or total via a pushbutton.
