ScioSense UFM-01 Ultrasonic Flow Sensing Module is based on contactless ultrasonic flow sensor technology. This sensing module features long-time reliability, up to 5% accuracy, 0l/h to 2000l/h sensing range, and 4MPa maximum water pressure. The UFM-01 contains no moving parts and enables precise control of liquid flow. This sensing module includes the sensor electronics, spool piece, connectors with standard ½″ thread, and a cable connector supporting single-wire and a UART interface. The UFM-01 sensing module is ideal for use with food-grade material and can directly measure drinking water flows. Typical applications include boilers, smart toilets, and coffee machines.
