Abstract: A wafer-type electromagnetic flow sensor includes a single-piece chassis having a pair of faces and a flow conduit extending between the pair of faces. Each face of the chasses includes a feature configured to engage a metal sealing ring. A non-conductive liner is disposed in the flow conduit of the single-piece chassis. A plurality of electromagnetic coils is configured to generate a flux into process fluid flowing through the flow conduit. A pair of electrodes is configured to electrically couple to the process fluid. A feedthrough assembly is configured to maintain process fluid pressure while allowing a plurality of electrical conductors to pass therethrough.

Abstract: A magnetic flowmeter for measuring a flow of a process fluid includes a flowtube arranged to receive the flow of the process fluid. First, second and third coils are arranged adjacent the flowtube. First and second electrodes are arranged to sense an electrical potential of the process fluid related to an applied magnetic field and a flow rate of the process fluid. The sensed electrical potential is used to calculate the flow rate of the process fluid through the flow tube.
