Abstract:
A method of fabricating a balance bar for a Coriolis flowmeter comprising the steps of:forming said balance bar as an elongated member having a radial center opening adapted to receive a flow tube, forming brace bars integral to said balance bar and having a center opening at each end of said elongated member, forming at least on void in said balance bar; forming at least one rib element integral to said balance bar to raise the lateral vibration frequency of said balance bar, said at least one rib element comprises ribs on the sides of said balance bar and oriented parallel to the longitudinal axis of said balance bar, and said ribs include elements that increase the cross sectional area of said balance bar in areas proximate said at least one voids that offset the tensile and compressive forces axially exerted on said balance bar whenever said flow tube attempts to change in length.
