Method for continuous measurement of liquid consumption e.g. for fuel, involves using continuously flow sensor with variable decrease of pressure, such as mass flow sensor

摘要

The method involves using a continuous flow sensor with variable decreasing of pressure, such as a mass flow sensor. The pressure behind the flow sensor is regulated by means of a pressure control valve to a constant value. During excess pressure of the selected liquid, it is tapped into a pressure control valve. The pressure control valve (9) has a housing, an element (40) which is subject to the variable strength pressure, which can be regulated. The element has a valve to decouple the pressure developing. This pressure control valve contains a reservoir to hold the liquid.
