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.

Centrifugal pump

A submersible pump assembly () includes a submersible pump () with a housing (), and a sensor capsule () with a hermetically sealed casing (). The sensor capsule () is releasably mountable at a sensor position () located at an outer face () of the housing () of the submersible pump (). The submersible pump () includes a primary coil () within the housing (). The sensor capsule () includes a secondary coil () within the casing (). The primary coil () and the secondary coil () are arranged to be inductively coupled with each other for wirelessly transferring data and/or power through the housing () and the casing () when the sensor capsule () is mounted at the sensor position ().
