Abstract
The described method and apparatus are relative to the indirect measurement of thermal energy delivered to numerous heating elements, part of one or several zones, for instance all the radiators in an apartment or all the radiant panels of single family quarters. The apparatus consists of a temperature sensor which outputs an electric signal depending upon the temperature of the carrying fluid in which it is immersed and corrected as a function of the type of heating unit used (radiators, fan-coils, radiant panels, convectors, etc.) since each system has a different thermal emission for an equal temperature of the fluid, an electronic circuit for processing the signal, valving devices for interception of the heat carrying fluid, and a counter device sensitive to the processed temperature signal, which device is sensitive to the added energy supplied, in a given time period to the various controlled rooms, each room having attributed to it its own thermal capacity by means of a programmable scaling circuit, when the interception valving devices for the heat carrying fluid let this fluid through.
