Beschreibung
Zusammenfassung:	A method for measuring the quantity of fluid ejected by an injector is described, characterised in that it provides the following steps: a) the pressure trend inside a chamber is detected during a certain number of stabilised injection cycles; b) the average liquid flow rate is measured; c) from the average liquid flow rate and from the difference between the instant pressures and the outlet pressure, parameters C 0 , C 1 and C 2 are obtained, which allow to calculate the instant flow rate of the injector; d) by employing the three parameters, the value of the instant flow rate is obtained on the basis of the pressure derivative with respect to time. Furthermore, a device is described to put the above-said method into practice.
