MAGNETIC FLOWMETER FLOWTUBE ASSEMBLY WITH INTERCHANGEABLE LINER/ELECTRODE MODULE

摘要

A flowtube assembly for a magnetic flowmeter is provided. The flowtube assembly includes a tube extending from a first mounting flange to a second mounting flange. Each of the first and second mounting flanges has a pipe flange facing surface for mounting to a respective pipe flange. A coil chamber is disposed outside the tube, between the first and second mounting flanges. The coil chamber has at least one coil located inside that is configured to generate a magnetic field within the tube. A liner/electrode module is positioned within the tube and has a non-conductive liner, at least one electrode and at least one electrode conductor. The non-conductive liner extends from the first mounting flange to the second mounting flange. The at least one electrode is positioned in the non-conductive liner to interact with a conductive process fluid. The electrode conductor extends from the at least one electrode to an interconnect tab disposed adjacent the pipe facing flange surface of one of the first and second mounting flanges. The liner/electrode module is positionable within the tube.
