特徴とする電磁流量計のアースリング。 A non-magnetic measurement tube with an insulated inner surface that is held in a flow tube through which a fluid flows through an earth ring, a pair of electrodes arranged oppositely on the diameter of the measurement tube, and a flow tube and an electrode. In an electromagnetic flowmeter, the flow rate is determined from an electric signal output between a pair of electrodes, with the potential of the ground ring as a reference, and a magnetic field generating means that applies a magnetic field perpendicular to the diameter of the ground ring. It is composed of an annular metal ring and a conductive resin ring made of carbon resin or the like that covers the inner peripheral part of the earth ring from one surface of the metal ring through the inner peripheral surface to the other surface. One end of the ring is welded at multiple locations on the outer periphery of the metal ring, and the other end is fixed to the outer circumferential surface of the measuring tube, so that the ring can be coaxially pressed against the end face of the electromagnetic flowmeter by a conductive holding spring that expands and contracts in the flow direction. The grounding ring of the electromagnetic flowmeter is a feature.
