摘要：
The present invention relates to a method for measuring a parameter characteristic of a heating and/or conditioning system (1) equipped with a primary hydraulic circuit (6) and a secondary hydraulic circuit (9) and wherein at least one operative fluid circulation pump (2) is provided operated by an electric motor and driven by a control electronic device (10). The method provides:
a starting measure of the flow rate of the circulating operative fluid carried out with closed delivery, immediately downstream the pump;
a subsequent measure of the flow rate of the circulating operative fluid in the sole secondary hydraulic circuit (9);
the first and the second measure being carried out with means associated to the control device (10) of the pump (2) so as to output an electric signal correlated with the percentage of additive of the circulating operative fluid or with a variation of the calorific power of the system.
