ABSTRACT:
The volumetric flow rate of a fluid is determined essentially independently of the properties of the fluid by guiding the volumetric fluid flow to be measured through an essentially linear flow resistor. An alternating flow of the fluid is superimposed on the volumetric fluid flow to be measured. Steady and alternating components of a pressure drop across the flow resistor are detected. A quantity representative of a property of the fluid is determined in response to the determined alternating component. The volumetric flow rate is calculated on the basis of the determined steady component and the quantity representing fluid property.
