Abstract (en)

[origin: WO2013079264A2] The invention relates to a method and to a device for a measuring a heat quantity, wherein, using an ultrasonic flow measuring device which works on the principle of difference in elapsed time, the flow of a fluid, the chemical composition of which is known, through the lumen of the pipe is determined, and wherein the temperature of the fluid is determined before and after a heat exchanger, wherein, for the first determination of the temperature of the fluid, the speed of sound of the fluid is determined by the ultrasonic flow measuring device, and a temperature outside of the lumen of the pipe is determined.
