Abstract: A polymeric flow tube assembly is provided. The flow tube assembly includes a flow conduit configured to allow fluid flow therethrough. A first coil is mounted with respect to the flow conduit and disposed about a first magnetic pole member. A second coil is mounted with respect to the flow conduit and is disposed about a second magnetic pole member. The second magnetic pole member is configured to cooperate with the first magnetic pole member to generate an electromagnetic field across a flow measurement aperture. First and second electrodes are positioned within the flow tube assembly to measure an electromotive force generated within a fluid in the flow measurement aperture. At least one of the first magnetic pole member, second magnetic pole member, first electrode and second electrode is formed, at least in part, of a polymer.
