CENTRIFUGAL PUMP

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)...

Beschreibung
Zusammenfassung:	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.
