HYDROCAL-M3

Compact heat/BTU meter capable of measuring the amount of energy used for heating and/or cooling individual utilities served by a centralized system.

The processing of the data related to the difference between the thermal fluid flow and the return (DT), along with the data relating to the volume of thermal fluid used by each utility, allows the calculation of the exact amount of energy consumed.

Approved according to the MID 2004 /22/CE MI004 and the EN1434 standard.
