Claims

[Scope of utility model registration request]

an electrode consisting of a head and a cylindrical body having an outer diameter smaller than the head; a plurality of electrodes arranged on a flat base and gathered around the axis toward a point on an axis perpendicular to the base; a stop metal fitting having a tongue-like piece, and a central through-hole having a diameter slightly smaller than the diameter of the electrode body formed by the tip of the tongue-like piece; a hole is provided in the tube wall for attaching the electrode; a measuring tube of an electromagnetic flowmeter, the inside of the hole of which the electrode mounting is also filled with a lining material made of an electrical insulator that coats the inner surface of the tube, and through which a fluid to be measured flows; an elastic mechanism; , the electrode is installed through the lining material inside the hole so that the tip of the body protrudes outside the measurement tube, and the stopper is configured to protrude above the outside of the measurement tube. The body of the electrode is arranged to pass through the central through-hole toward a point on the axis of the base toward which the tongue-shaped piece is directed, and the elastic mechanism
The electrode is interposed between the measuring tube and the base of the stopper so as to press the stopper toward the distal end of the body with the tip of the tongue-like piece engaged with the body. An electrode mechanism for an electromagnetic flowmeter, characterized in that the electrode mechanism prevents the electrode from falling into the measuring tube.
