Danfoss Sonometer 30 

The Danfoss SonoMeter 30 is a range of ultrasonic, compact energy meters intended for measuring energy consumption and cooling applications for billing purposes. Available in DN15 to DN50. The meters are designed for remote meter read-out (AMR). SonoMeter 30 energy meters consist of an ultrasonic flow sensor, a pair of Pt500 temperature sensors and a calculator with integrated circuits for temperature measurement, flow calculation and energy calculation.
