Abstract: A magnetic flowmeter for measuring flow rate of a process fluid, includes a magnetic coil arranged to apply a magnetic field to the process fluid. A pair of electrodes are electronically coupled to the process fluid and arranged to sense a voltage induced in the process fluid related to the applied magnetic field and the flow rate of the process fluid. A molded flow tube of a non-conductive material is arranged to receive a flow of the process fluid. The flow tube is molded around the magnetic coil and the pair of electrodes and is configured to support the magnetic coil and the pair of electrodes. Flow meter circuitry is configured to apply a current to the magnetic coil and receive the resultant voltage sensed by the pair of electrodes.

Abstract: A magnetic flowmeter for measuring flow of a process fluid includes a meter body having an opening formed therein. The meter body is configured to be inserted in-line between process piping which carries the process fluid. A moveable extension is coupled to the meter body and configured to extend into the process piping. A coil of wire is carried by the extension and configured to generate a magnetic field. A pair of electrodes sense an EMF in the process fluid generated as a function of the applied magnetic field and flow of the process fluid.

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.
