Abstract
In a method for continuous measuring of dynamic fluid consumption, particularly fuel, the pressure beyond the flow sensor is adjusted to a constant value by means of a pressure regulator by using a continuously-operating flow sensor with variable pressure drop, preferably a mass flow sensor. Fluid is guided into the pressure regulator after exceeding a discretionary pressure to allow continuous, accurate, as well timely and highly discriminating consumption measuring with regulated exit pressure for the fluid even at a back-flow of short duration or during temperature-related expansion of the fluid. A pressure regulator () provided for this purpose has a housing (), which contains an element () biased by a changeable force whereby the element () is coupled to a valve arrangement () that is also arranged in the housing () for the fluid to build up pressure therein. The pressure regulator () contains a catch volume for the fluid.
