ABSTRACT:
An electromagnetic flowmeter comprises a ceramic measuring tube through which fluid to be measured flows, a pair of electromagnetic coils disposed on the outer surface of the measuring tube in the central region thereof at diametrically opposite positions and generating a magnetic field in a direction perpendicular to the direction of flow of the fluid, a pair of measuring electrodes fixed to the outer surface of the measuring tube in the central region thereof at diametrically opposite positions and having electrode axes perpendicular to both the direction of flow of the fluid and the direction of the magnetic field, and a pair of metallic shields fixed to the outer surface of the measuring tube in surrounding relation to the measuring electrodes. A pair of the measuring electrodes and a pair of the metallic shields are fixed to the ceramic measuring tube by a reaction product due to an interface reaction with the ceramic measuring tube under heating.
