Claims

[Scope of utility model registration request]

(1) A measurement tube for passing fluid arranged in an outer casing that also serves as a core, a pair of electrodes installed perpendicularly to the tube axis on this measurement tube, a line connecting this pair of electrodes, and the measurement described above. One magnetic pole end of a magnetic pole around which a coil is wound is placed on the diameter axis perpendicular to the tube axis of the tube, and the other end of the magnetic pole is arranged with respect to the measurement tube, and the other end also serves as a part of the outer casing, and the diameter axis is aligned with the diameter axis. In an electromagnetic flowmeter comprising a pair of excitation parts that generate a magnetic field in a direction, the part around which the coil of the magnetic pole is wound has a smaller diameter than the end of the magnetic pole facing the measuring tube, An electromagnetic flowmeter characterized by the following:

(2) The electromagnetic flowmeter according to claim 1, which is a registered utility model, characterized in that the magnetic pole end facing the measuring tube is formed to be detachable from the magnetic pole.

(3) A utility model characterized in that the magnetic pole end facing the measuring tube is formed in a size and shape that makes contact with the inner surface of the outer casing, and doubles as an electrostatic shield plate that shields noise from the coil to the electrode. An electromagnetic flowmeter according to claim 1.
