The UFM-02 is a family of ultrasonic flow sensing modules designed for pipe diameters ranging from 3/8” to 1.5”.

These modules use ScioSense’s static, contactless ultrasonic technology, eliminating the need for moving rotors found in traditional Hall sensor-based flow sensors.

As a result, the UFM-02 has no moving parts, which extends its operational lifetime when used according to specifications. The devices offer multiple interface options, such as SPI and pulse output, making them easy to integrate into embedded systems.

They are suitable for food-grade applications, can directly measure drinking water flow, and provide at least ±5% accuracy at higher flow rates.

Additionally, the UFM-02 can detect very low flow rates, enabling applications like leakage detection and precise control of water flow and temperature in various appliances.
