Heat meter system including means for separate, automatic registration of heat consumption
Abstract
Abstract A heat meter (1) for registration of heat consumption on the basis of a temperature measured is provided which with a view to obtaining direct recording and/or display of the consumption is arranged as a unit which at least comprises temperature measuring means (20, 21), a time generator (23), an arithmetic unit (22) and a programmable store (25) which is adapted to store at least the registered heat consumption. The arithmetic unit (22) is adapted to receive information from said parts sufficient for it to compute a direct index of the heat consumption, e.g. stated in kWh. A system for separate registration of the heat consumption of a plurality of heat emitting elements, such as radiators, for automatic, specified calculation of the total heat consumption of several heat emitting elements comprises a heat meter (1) of the above-mentioned type mounted in connection with each of the heat emitting elements and comprises a portable data accumulator (14), which is adapted to be temporarily connected to these heat meters (1) in succession to transmit the heat consumption recorded in each heat meter ( 1) to a store (34) in the data accumulator (14). The data accumulator (14) also comprises coding means (31, 32, 33) to read data into the store (25) of a heat meter (1).
