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： An object of the present invention is to provide an electromagnetic flowmeter designed to use a smaller excitation device and applicable to measurement on tubular channels of various sectional shapes. The electromagnetic flowmeter 10 includes an excitation device 11 for forming a magnetic field perpendicular to an outer wall 11b of a tubular channel 1, and a pair of electrodes 2a and 2b for measuring an electromotive force generated by the movement of the electroconductive fluid across the magnetic field. The electrodes 2a and 2b and two magnetic poles of the excitation device 11 are collectively placed on the outer wall 1b at one side of the tubular channel 1.
