摘要： An insert-type electromagnetic flow sensor is disclosed. The flow sensor comprises an insert (12), first and second electrodes (44, 45) supported on opposite sides of the insert and a drive coil (63) housed in the insert. The drive coil is offset from a midpoint (62) between the first and second electrodes and/or a width of the drive coil between the first and second opposite sides at least partially overlaps with respective inner portions of the first and second electrodes. The drive coil includes at least five turns.

摘要： A centrifugal pump unit (1) is disclosed having a body (4) that includes a suction connection (5), a pressure connection (6) and a pump chamber (7) connecting the suction and pressure connections. The centrifugal pump unit further includes an impeller (8) disposed in the pump chamber and at least one electromagnetic flow sensor (3) arranged to measure flow in at least a part of the suction connection and/or pressure connection and/or pump chamber for determining a flow rate of a fluid through the centrifugal pump unit or for determining a control signal equivalent of the flow rate for control purposes.
