Patent ID: 7930816

Claim:
A method of manufacturing an electromagnetic flow meter insert assembly for insertion within and along a flow conduit, the method comprising: providing a molded insert formed from a deformable material, the molded insert comprising, in an un-deformed state: an inlet for receiving fluid flowing along the flow conduit, the inlet defining an inlet bore in which the received fluid can flow, an outlet for outputting fluid that flows through the insert, the outlet defining an outlet bore in which the output fluid can flow, and a measuring section between the inlet and the outlet, the measuring section defining a measuring section bore, wherein the cross-sectional area perpendicular to the flow direction of the measuring section bore is smaller than the cross-sectional areas perpendicular to the flow direction of the inlet bore and the outlet bore, wherein the difference between the cross-sectional areas of the measuring section bore and the inlet and outlet bores defines a space for placing an electromagnetic coil between the measuring section and the flow conduit; providing at least one reinforcing component; arranging the reinforcing component around the measuring section but not around the inlet or the outlet; and bonding the reinforcing component to the exterior surface of the measuring section to reinforce the measuring section against deformation under the application of pressure, wherein the bonding occurs prior to the insert being placed within and along the flow conduit.
