A flowtube assembly (10) for a magnetic flowmeter is provided. The flowtube assembly (10) includes a tube (12) extending from a first mounting flange (14) to a second mounting flange (16). Each of the first and second mounting flanges (14,16) has a pipe flange facing surface (15, 17) for mounting to a respective pipe flange. A coil chamber (42) is disposed outside the tube (12), between the first and second mounting flanges (14,16). The coil chamber (42) has at least one coil (40) located inside that is configured to generate a magnetic field within the tube (12). A liner/electrode module (22) is positioned within the tube (12) and has a non- conductive liner, at least one electrode (50, 51) and at least one electrode conductor (76,78). The non-conductive liner extends from the first mounting flange (14) to the second mounting flange (16). The at least one electrode (50, 51) is positioned in the non-conductive liner to interact with a conductive process fluid. The electrode conductor (76,78) extends from the at least one electrode (50, 51) to an interconnect tab (24) disposed adjacent the pipe facing flange surface of one of the first and second mounting flanges (14,16). The liner/electrode module (22) is positionable within the tube (12). |
