摘要： An electromagnetic flow meter comprises: an excitation member (5) in which a plurality of magnets (5a, 5b, 5c) are arranged spaced apart from one another along an outer circumferential surface of a flow channel (1) through which liquid metal flows, and in which a magnetic field is formed in a direction perpendicular to the outer circumferential surface of the flow channel (1); and electrodes (6a, 6b) provided between the magnets (5a, 5b, 5c) of the excitation member (5), for measuring the voltage generated when the liquid metal crosses the magnetic field. A pulse excitation electric-current supply device (7a) for supplying a pulsed excitation current to the excitation member (5) is provided, whereby a flow speed distribution can be suppressed from being generated in the circumferential direction of the channel (1) even when the flow speed of the liquid metal is low, and the flow rate can be accurately measured.

摘要： One embodiment of an electromagnetic flow rate measurement system includes electromagnetic flowmeters arranged at intervals from one another in the peripheral direction of an annular flow passage 1 in which an electric conductive fluid flows. Each of the electromagnetic flowmeters comprises: an excitation member that has magnets arranged at intervals from one another in the outer peripheral surface of the annular flow passage so as to form a magnetic field in the direction perpendicular to the outer peripheral surface of the annular flow passage; and electrodes that are provided between the magnets of the excitation member and between the magnets of the excitation member so as to measure voltage generated when the electric conductive fluid crosses the magnetic field. The polarities of the magnets at the end portions of the closest excitation members of the adjacent electromagnetic flowmeters are opposed to each other.
