Abstract: A magnetic flowmeter comprises a pipe section for process flow, a coil for generating a magnetic field across the pipe section, a current source for energizing the coil to generate the magnetic field at a coil drive frequency, and electrodes for sensing voltage induced across the process flow by the magnetic field. A processor calculates a function of the sensed voltage and generates a flow output based on the function. The processor adjusts an operating parameter of the flowmeter, such as electrode voltage sampling period, the coil drive frequency, or a phase shift, as a function of a sensed electrode-to-electrode or electrode-to-ground complex impedance.

Abstract: A polymeric flow tube assembly is provided. The flow tube assembly includes a flow conduit configured to allow fluid flow therethrough. A first coil is mounted with respect to the flow conduit and disposed about a first magnetic pole member. A second coil is mounted with respect to the flow conduit and is disposed about a second magnetic pole member. The second magnetic pole member is configured to cooperate with the first magnetic pole member to generate an electromagnetic field across a flow measurement aperture. First and second electrodes are positioned within the flow tube assembly to measure an electromotive force generated within a fluid in the flow measurement aperture. At least one of the first magnetic pole member, second magnetic pole member, first electrode and second electrode is formed, at least in part, of a polymer.

Abstract: A flowtube assembly for a magnetic flowmeter is provided. The flowtube assembly includes a flowtube configured to receive a flow of process fluid. A magnetic core is mounted relative to the flowtube and includes a plurality of layers of a magnetically permeable material. Each layer is substantially planar and is electrically insulated from others of the plurality of layers. A coil is disposed to generate a magnetic field having field lines that are substantially orthogonal to the plane of each layer.

Abstract: 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.
