Abstract
A method for determining a flow volume of a fluid delivered by a pump. The flow volume is determined as a function of predefined pump information depending on a pump geometry, rotation speed information, which correlates with the rotation speed of the pump, and pressure information, which correlates with a differential pressure at the pump.

A method for determining a flow volume of a fluid delivered by a positive-displacement pump, wherein the flow volume is determined as a function of predefined pump information, which is dependent on a pump geometry, a rotation speed information, which correlates with the rotation speed of the pump, and pressure information, which correlates with a differential pressure at the pump, wherein, as additional information, an operating current and/or a shaft torque of the pump are registered, wherein the flow volume is determined by the function which further comprises the additional information, wherein the flow volume is calculated by subtracting a leakage volume flow, which is determined as a function of the pressure information and a function of the additional information, from a theoretical delivery volume flow, which is determined as a function of a pump volume predefined by the predefined pump information and the rotation speed information.
