Abstract: A method serves for detecting the flow rate of a centrifugal pump, wherein the rotation speed of the pump or of the motor driving the pump, a hydraulic variable of the pump, typically the delivery pressure and an electrical variable of the drive motor, for example the electrical power are determined, and the flow rate is evaluated by way of these variables. For this, variables dependent on the flow rate are determined by way of a mathematic linking of terms of equations describing physical relations of the pump and drive motor, wherein one term contains the rotation speed of the pump and a hydraulic variable of the pump and another term contains an electric or mechanical variable of the drive motor of the pump and the rotation speed of the pump. The flow rate is determined by way of the functional relation between the flow rate and the dependent variable.
