A little heat/BTU meter that can calculate how much energy is utilized to heat or cool each utility that is served by a centralized system.
Calculating the precise amount of energy spent requires processing data pertaining to the difference between thermal fluid flow and return (DT), as well as data pertaining to the volume of thermal fluid used by each utility.
MID 2014/32/UE MI004 and EN1434 standards-compliant; approved.
