BMeters BSP Screwed EN1434 5 M-Bus Mechanical Thermal Energy Meter
HYDROCAL-M4 is a compact thermal energy meter that measures the amount of energy used for heating or cooling the water supplied to individual tenants served by centralised heating/cooling systems.
The processing of data related to the difference between the temperature of the supply and that of the return, along with the data related to the volume of water used by each tenant, allows to calculate the exact amount of energy actually used.
