High pressure wafer style magnetic flowmeter

A wafer-type electromagnetic flow sensor comprising:

• a single-piece chassis having a pair of faces, a flow conduit extending between the pair of faces, wherein each face includes a feature configured to engage a metal sealing ring, and a single aperture of the single-piece chassis extending from the flow conduit to an outside diameter;
• a non-conductive liner disposed in the flow conduit of the single-piece chassis;
• a plurality of electromagnetic coils configured to generate a flux into process fluid flowing through the flow conduit;
• a pair of electrodes configured to electrically couple to the process fluid;
• and
• a feedthrough assembly configured to maintain a pressure of the process fluid while allowing a plurality of electrical conductors to pass therethrough, wherein the feedthrough assembly is disposed in and seals the single aperture.
