An injection quantity measurement arrangement, esp. for fuel, has a closed pressure container (1) of defined vol. for storage of the fluid injected by a pump (6), a detector of the fluid press. changes inside the container and a device which determines the quantity of fluid injected on the basis of the pressure change signal. The injection pump (6) performs multiple fluid injections during the injection process. A computer (16) inititates an individual pressure change measurement for each injection and processes the measurement results. USE/ADVANTAGE - Enables accurate measurement of quantities of fuel injected at high speed, with temp. effects weakened.
