Belimo 22PE-1UG - thermal energy meter

Belimo 22PE-1UG thermal energy meter

The device measures thermal energy based on volumetric flow and the temperature difference between the supply and return in a closed heating or cooling circuit. It can operate as a heat meter, cooling meter, or combined heating and cooling meter. The flow sensor uses the ultrasonic measurement principle; one temperature sensor is integrated and the other is external.
