The Model UFM compact ultrasonic flow meter is a low-cost, clamp-on, ultrasonic flow meter that uses the transit-time difference method to measure flow rates in pipes non-invasively. It has a compact and lightweight design, featuring an easily installed, all-in-one, clamp-on unit. This unit can measure velocity and flow in pipes with outside diameters ranging from 24.89 to 117.35 mm. The screen offers easy-to-read text with a convenient backlight for visual comfort. This model comes with a volume pulse and 4-20 mA flow rate output.

Two sensors located in the guiderail are placed on the exterior of the pipe, and each transmits an ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate. The difference in the transit times of the two pulses is used to calculate the flow rate, and the use of transit time allows the flow meter to be unaffected by pressure or temperature changes.

Applications include heat metering; chilled water metering and monitoring; as well as potable water and process water metering and monitoring.
