A method for continuous measurement of the dynamic fluid consumption of a consumer by use of a two-way flow sensor, particularly the measurement of gaseous or liquid fuel, and possibly a conditioning device, whereby the pressure is reduced to a constant exit pressure downstream from the flow sensor. A minimum quantity of fluid is fed through the pressure regulator at any desired time whereby fluid is continuously returned in variable quantities from the region of constant exit pressure to the region between the flow sensor and the pressure regulator to make possible a continuous, accurate and timely highly defined consumption measurement with controlled exit pressure for the fluids using an open system which is able to maintain pressures in the entire line system even at highly dynamic consumption changes and which does not allow the formation of a multiphase flow. The device for to carrying out the method is provided with a pressure control device downstream from the flow sensor and a connecting line with a pump leading from the region behind the pressure control device to the region between the flow sensor and the pressure control device.
