  • Patent number: 12258970
    Abstract: The centrifugal pump includes a flow measuring device (3) adapted to measure a delivery flow through the pump by means of a turbine wheel (32) including at least one permanent magnet (42). The flow measuring device includes at least one magnetic flux sensor (50, 51) arranged in a sensor housing (48) mounted in an outer wall of the pump casing (2). A rotatable disc (52) is fixed on a pump shaft and includes at least one permanent magnet (53). 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.

  • Patent number: 11879445
    Abstract: A submersible pump assembly (1) includes a submersible pump (2) with a housing (3), and a sensor capsule (4) with a hermetically sealed casing (5). The sensor capsule (4) is releasably mountable at a sensor position (6) located at an outer face (7) of the housing (3) of the submersible pump (2). The submersible pump (2) includes a primary coil (8) within the housing (3). The sensor capsule (4) includes a secondary coil (9) within the casing (5). The primary coil (8) and the secondary coil (9) are arranged to be inductively coupled with each other for wirelessly transferring data and/or power through the housing (3) and the casing (5) when the sensor capsule (4) is mounted at the sensor position (6).
