Abstract
The centrifugal pump includes a flow measuring device () adapted to measure a delivery flow through the pump by means of a turbine wheel () including at least one permanent magnet (). The flow measuring device includes at least one magnetic flux sensor () arranged in a sensor housing () mounted in an outer wall of the pump casing (). A rotatable disc () is fixed on a pump shaft and includes at least one permanent magnet (). The flow measuring device is adapted to measure the delivery flow on the basis of a first measurement signal generated by the at least one magnetic flux sensor as a result of the rotation of the turbine wheel and to include in the measurement of the delivery flow a second measurement signal generated by the at least one magnetic flux sensor as a result of the rotation of the rotatable disc.
