FIELD: instrumentation.
SUBSTANCE: invention relates to thermotechnical measurements and can be used for measurement of amount of consumed heat energy in heat supply systems. According to the offered method using Newton-Richmann law the difference of average temperatures of the heating device and air is measured which is multiplied by the heating device thermolysis coefficient. The heating device thermolysis coefficient is found by interruption in supply of the heat carrier into the heating device with subsequent measurement of temperature dependence of the cooled-down heating device, finding of rate of change of temperature and calculation of the named coefficient. After finding of the thermolysis coefficient the heating system is activated and the heat power is calculated.
EFFECT: improvement of accuracy of measurement of heat energy supplied by a heating device.
