ABSTRACT:
An electromagnetic flowmeter characterized by comprising a measuring tube through which fluid flows, a pair of electrodes installed to a wall surface of the measuring tube so as to face each other, electrode mounting holes of a funnel shape made at a specified angle in an inside wall surface where the electrodes are installed so as to face each other, packing that has a tilt angle different from that of the funnel-shaped portion of the electrode mounting hole and that has a penetration in its center which allows an insertion of the electrode, an elastic member installed to one end of the electrode for pulling the electrode in a longitudinal direction with a particular force and giving & particular elasticity to the electrode, and a fastening member for fastening the electrode to the measuring tube with a screw via the packing.
