<p>The procedure is for static measurement of the calorific power supplied by a boiler (11) to a receiver (12), such as a number of radiators, by a heat carrying fluid, such as hot water, running through an outgoing pipe (13) and a return pipe (14). Two impedances (Z1,Z2) of fluidic or hydraulic type are mounted in parallel and branched from one of the pipes in series with the receiver. A heat exchanger (15) having two pathways is connected such that it is traversed by a fraction of the fluid of each of the pipes. The procedure first measures the temp. of the fluid in the impedances. Then the mass differential enthalpy of fluid is measured at the inputs and outputs of the two pathways of the heat exchanger and at the input and output of the receiver. Finally an algebraic calculation is performed on the measured thermal values to deduce a value proportional to the calorific power supplied to the receiver.</p> |
