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 includes a pipe with a non-conductive PTFE liner, magnetic coils to generate a magnetic field, and electrodes in contact with the fluid on opposite sides of the pipe. The electrodes comprise conductive PTFE patch electrodes bonded to the non-conductive PTFE liner so that an inner end of each patch electrode is exposed to fluid flowing through the interior pipe and an outer end of each patch electrode is aligned with an electrode hole in the pipe.
