Abstract
An electronic integration calorimeter comprises a temperature difference detector for detecting a difference between the temperature of a heat medium flowing into a heat load and the temperature of the heat medium flowing out of the heat load, and a flow pulse generator for generating a flow pulse signal having the number of pulses proportional to the flow of the heat medium. The flow pulse signal of said flow pulse generator is shaped by a pulse shaping circuit into a flow pulse signal having a predetermined pulse width. A temperature difference pulse generator is adapted to generate a temperature difference pulse signal having the number of pulses proportional to the output voltage of the temperature difference detector and to be controlled by the shaped flow pulse signal so as to generate a pulse signal obtained by ANDing together the temperature pulse signal and the flow pulse signal. The ANDed pulse signal is supplied to a counter where pulses included in the pulse signal are counted.
