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