Abstract (en)
[origin: EP0777292A1] The heat consumption measuring equipment involved uses a radio means for measuring the figure recorded by a counter, and a temperature sensor (10) thermally connected to the heat consumer or heating body. This sensor is connected through an A/D converter (12) with a digital multiplier (14), receiving the output signal of a ROM (16) with its characteristic values, and sending its results to the integrating circuit (22). The figures summed are display on the indicating panel (24). The results are sent also to a modulator (32) and its output is sent to the UHF transmitting circuit (34) for passing to the antenna unit (36). This unit includes a feed inductance (40) with a condenser (42), and this resonance circuit connects the two terminals, transmitting to a central station.
