Energy counter

EHM1 energy counter has been developed to measure thermic energy exchanged in integrated heating and colling installations. the computation of the thermic temperature done by the electronic reading of the volume of water passed through the flowmeter, and the temperature difference detected by two PT500 thermo sensors, the first placed on the direct flow and the second on the return flow. RS232, RS485, and M-Bus interfaces offer a smart integrated reading network.
