Dwyer Instruments UFM2-14 | Compact ultrasonic flowmeter | Pulse and 4-20 mA outputs | 3/4 to 4" (25 to 115 mm) pipe
These affordable clamp-on ultrasonic flowmeters are called Model UFM2-14 Compact Ultrasonic Flowmeters. The UFM2 measures velocity and flow in pipes with outer diameters ranging from 3/4 to 7" (25 to 180 mm) by utilizing the transit-time difference method. This type has an output flow rate of 4–20 mA and a volume pulse.
