Abstract

The invention relates to a centrifugal pump with a suction connection and a pressure connection (3, 5) and a flow sensor (11) measuring the volume flow, wherein the flow sensor is detachably connected to the wall (7) of the suction (7) or pressure connection and extends with a part (12) sensing the fluid flow, particularly the liquid flow, into the connection channel.
