The FDT100 Series flowmeter uses transit-time ultrasonic technology — two flow sensors alternately transmit and receive a signal and "time of flight" measures flow rate. The battery-powered flowmeters have no moving parts, minimal pressure loss, and filtration is unnecessary. Long-term stability and a wide measurement range facilitate consumption and leakage monitoring. The meters are available in 150-lb ANSI and DIN styles with a choice of integral or remote electronics that display flow rate or total at the push of a button.
