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 electrically couple to the process fluid and are 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 flow tube of a non-conductive material is arranged to receive a flow of the process fluid therethrough. The flow tube carries the magnetic coil and the pair of electrodes. Flow meter circuitry applies a current to the magnetic coil and receives the voltage sensed by the pair of electrodes. A magnetic field spreader is positioned proximate the magnetic coil and is arranged to spread the magnetic field emanating from the magnetic coil and direct the magnetic field into the flow tube. An exterior wrapper extends around the assembly and completes a magnetic circuit.

First and second electrodes are disposed within the pipe and electrically coupled to the process fluid and configured to sense an electromotive force (EMF) induced in the process fluid due to the applied magnetic field and flow of the process fluid. Input circuitry is coupled to the first and second electrodes and provides an output related to the sensed EMF. Diagnostic circuitry coupled to the input circuitry is configured to identify a saturation related condition and responsively provide a diagnostic output. In another embodiment, saturation prevention circuitry prevents saturation of the input circuitry.

Abstract: A process variable transmitter is configured as a flowmeter for measuring flow of a process fluid through a conduit. The transmitter includes a pitot tube extending into the conduit which creates a differential pressure in the process fluid due to flow of the process fluid. An upstream process variable sensor is mounted on the pitot tube and coupled to the flow of process fluid to sense an upstream process variable of the process fluid. A downstream process variable sensor is mounted on the pitot tube downstream of the upstream process variable sensor and coupled to the flow of process fluid to sense a downstream process variable of the process fluid. Measurement circuitry determines the flow of the process fluid based upon the upstream process variable and the downstream process variable.
