Abstract:
A method for determining characteristic values of an electrometrically driven centrifugal pump assembly with a speed controller, said assembly being integrated in an installation, includes determining characteristic values by way of electrical variables of the motor and of the pressure produced by the pump, with which one successively runs to at least two different operating points of the pump. Delivery rates are determined in the installation at the run-to operating points, and the characteristic values are determined based on the delivery rates.
