Abstract
An electromagnetic flowmeter which includes a pair of electrodes molded of electrically-conductive synthetic plastic material disposed at diametrically-opposed points in a flow tube through which the fluid being metered passes to intercept a magnetic field, thereby inducing a voltage in the electrodes that is a function of flow rate. The inner wall of the tube is protectively covered by an insulating liner molded of a synthetic plastic material having an affinity for the electrode material and fused to the periphery thereof to define a monolithic conduit which is leak-proof.
