Individual flow sensor for most common applications

SonoSensor™ 30 is an ultrasonic flow sensor designed for heating, cooling or combined heating/cooling applications in medium sized local and district energy systems. Combined with the InfoCal™ 9 energy calculator it offers normal compact meter functionalities for medium sized hydronic applications.

The sensor is MID Class II certified.

SonoSensor™ 30 is also optionally used in our Danfoss Digital Hydronics™ solutions. The actual flow measurements are provided as digital data to a Building Management System (BMS) via the NovoCon® S or M digital IoT actuator.
