Abstract: A composite flow tube liner includes a cylindrical substrate and an interior layer. The cylindrical substrate includes a plurality of perforations and is configured for installation within a flow tube assembly of a magnetic flowmeter. The interior layer includes a fluoroelastomer and covers an interior surface of the substrate. The interior layer extends into the perforations of the cylindrical substrate, which secures the fluoroelastomer to the cylindrical substrate.

Abstract: A magnetic flowmeter for sensing process fluid flow includes a flow tube configured to receive the process fluid flow there through and a plurality of electrodes disposed to contact process fluid. At least one electromagnetic coil is disposed proximate the tube. A flow tube liner is provided in the flow tube having an interior surface configured to contact process fluid and an exterior surface mounted to the flow tube. The flow tube liner has at least one adhesion feature in the exterior surface which promotes adhesion between the flow tube liner and the flow tube. A method is also provided.
