Product news

ScioSense has released an all-in-one ultrasonic flow sensor module that offers an easy-to-use and reliable alternative to
traditional mechanical flow sensors.

The UFM-01 is a complete unit including the sensor electronics, spool piece, connectors with standard ½” thread, and a
cable connector supporting single-wire and UART interfaces. The module is based on ScioSense contactless ultrasonic flow sensor technology, which does away with the rotors and other mechanical parts in traditional Hall sensor-based flow
sensors. Because these mechanical parts are prone to corrosion and wear and tear, they can be unreliable, and offer a limited operating time before failure. By contrast, the ultrasonic UFM-01 contains no moving parts and offers an unlimited lifetime when operated according to datasheet specifications.

The UFM-01 is suitable for use with food-grade material, and can directly measure drinking water flows. Accurate to at least ±5 % at flow rates above 60 l/hr, the UFM-01 enables precise control of liquid flow and – via a built-in temperature sensor – liquid temperature in the control systems of products such as boilers, smart taps, beverage brewing machines and more.

Norbert Breyer, Director of Marketing and Sales at ScioSense, said: ‘Engineers recognise that ultrasonic sensors are
superior to the traditional mechanical sensors used to measure flow rates. Integrating a discrete ultrasonic sensor IC with a spool piece requires some know-how in ultrasonic technology. With the UFM-01, ScioSense has already done the
integration, so this gives users a quick and easy way to implement an ultrasonic flow sensor in their application.’

Accurate, low-power measurement
Operating from a 5 V supply, the UFM-01 draws just 5 mA. It can measure flows at rates from 0 l/hr to 2000 l/hr. Between 0 l/hr and 60 l/hr, measurement accuracy is at least ±10 %.

The compact module of 60mm length is available now directly from ScioSense, or from any authorised distributor.
