Product Details

Main Features

●Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flowing volume through meter.

●Flowing volume signal comes from flow sensor, temperature difference comes from temperature sensor pair,as result the calculator will calculate heat according to the flowing volume and temperature difference.

●Measurement unit: Kwh, Gcal for option

●For Ultrasonic heat meter, communication via M-BUS, RS-485 for option.

Measuring Features:

Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flow volume through meter. Flow volume signal comes from flow sensor, temerature difference comes from temperature sensor pair, as result the calculator will calculate heat according to the flowing volume and temperature difference.

 

Water pressure: ≤1.6Mpa
Measuring accuracy: Class 2
The max tolerance is shown in the curve below:
E=±(3+4Δθmin/Δθ+0.02qp/q)%
Therein,Δθmin means the minimum temperature difference, and Δθthe actual temperature difference.
