Abstract: A flowtube assembly for a magnetic flowmeter is provided. The flowtube assembly includes a flowtube configured to receive a flow of process fluid therethrough. A magnetic core is mounted relative to the flowtube and includes a stem extending from the flowtube to a pair of arms. Each of the arms extends away from the stem. A spool having a plurality of magnetic windings is disposed about the stem and spaces the plurality of windings from the flowtube.

Abstract: A magnetic flowmeter for sensing process fluid flow is provided. The flowmeter includes a tube configured to receive the process fluid flow therethrough. A plurality of electrodes is disposed to contact process fluid. At least one electromagnetic coil is disposed proximate the tube. Flowmeter electronics are configured to drive a current through at least one electromagnetic coil and to sense a signal developed across a plurality of electrodes disposed to contact process fluid. A flexible circuit module is disposed proximate the tube, and has at least one flexible circuit containing a plurality of electrical traces electrically coupled to the flowmeter electronics. The at least one electromagnetic coil includes a first coil in the flexible circuit module that is coupled to the electrical traces.
