Polymeric magnetic flowmeter flow body assembly

A polymeric flow body assembly comprising:

• a polymeric flow body having a measurement bore with a bore curvature;
• a first coil mounted with respect to the measurement bore and disposed about a first magnetic pole member disposed to contact fluid in the measurement bore;
• a second coil mounted with respect to the measurement bore and disposed about a second magnetic pole member that is also disposed to contact the fluid in the measurement bore, wherein the second magnetic pole member is configured to cooperate with the first magnetic pole member to generate an electromagnetic field across the measurement bore;
• first and second metal electrodes positioned within the flow body assembly to contact a fluid in the measurement bore and to measure an electromotive force generated within the fluid, wherein the first and second metal electrodes taper toward a center of the polymeric flow body assembly;
• wherein at least one of the first magnetic pole member and second magnetic pole member is formed, at least in part, of the polymer;
• and
• wherein each of the first and second metal electrodes and each of the first and second magnetic pole members has a curved end with the bore curvature.
