Electromagnetic flowmeter

摘要

An electromagnetic flowmeter uses a cylindrical inner tube including an electrode, an excitation coil and an inner portion of an electrical connector with the inner portion being located on an outer circumferential surface of the tube and electrically connected to the electrode and the coil, an outer tube housing the inner tube along its axis and having an access opening extending transversely through the outer tube housing and an electrical connector support externally inserted through the access opening for supporting an outer portion of the electrical connector to selectively mate with the first portion of the connector to provide separate electrically conductive paths through the connector for connections to the electrode and the excitation coil.
