<p>A calorimetric device is for measurement of a quantity of heat generated in a heat exchanger from a fluid flow, with a throughput meter whose output is a pulsed voltage of variable frequency and temp. sensors for exchanger input and output flow temp. measurement is made with standardised and have economical components and enables optional accuracy selection dependent on the number of binary places used. The variable frequency divider controlled by a signal representing the input/output temp. difference with which the division ratio varies.</p> |
