Circuits for separately measuring the thermal energy consumption of a plurality of consumer units fed from a central power station

摘要

The invention relates to a circuit for separately measuring the thermal energy consumption of a plurality of consumer units fed from a central power station, with the aid of thermal energy meters assigned to each consumer unit, which in each case contain a feed temperature sensor, a return temperature sensor, a volumetric meter and an arithmetic unit. The invention is characterised in that the individual arithmetic units are excluded from the thermal energy meters, and in that a common arithmetic unit is connected downstream of the remaining temperature sensors and volumetric meters assigned to the individual consumer units. <IMAGE>
