B-meters HYDROSPLIT-M3 Split thermal energy calculator

To calculate the amount of energy needed for heating and/or cooling, use a separate heat/BTU calculator.

Useful in systems with pipes larger than DN20- 34 " and easily connectable to flow meters with pulse output.

Calculating the precise amount of energy utilized requires processing data on the difference in thermo-vector fluid temperature between the supply and return (DT) along with information on the volume of thermo-vector fluid used.

MID 2014/32/UE MI004 and EN1434 standards-compliant; approved.
