摘要： PROBLEM TO BE SOLVED: To restrain an electromotive force in a molten metal inside measured between electrodes from getting low in accompaniment to increase of an apparent wall thickness of a protection member 24 or an inner core 21, and to stabilize the electromotive force measured between the electrodes.
SOLUTION: This electromagnetic flowmeter for the molten metal has a cylindrical duct 11 for moving the molten metal, a pair of magnetic poles 16, 16 arranged opposedly with the duct 11 therebetween to form a magnetic flux inside the duct 11, the pair of electrodes 12, 12 arranged opposedly with the duct 11 therebetween to output a voltage generated in the molten metal moving in the duct 11 along a direction cutting the magnetic flux. The inner core 21 passing the magnetic flux between the magnetic poles 16, 16, and the protection member 24 for protecting the inner core 21 are inserted into the duct 11 to form an insulation layer 22 between the inner core 21 and the protection member 24. An inner duct 18 is also inserted into the duct 11 to form an insulation layer 23 between the inner core 21 and the inner duct 18.
