Abstract:
In a Coriolis flowmeter having a flow tube and a balance bar that are adapted, when in use, to be vibrated in phase opposition in a driven plane to generate a Coriolis response in said vibrating flow tube representing information pertaining to material flowing through said vibrating flow tube, said flow tube comprises a center portion and an extension at each end;said Coriolis flowmeter comprising: a case surrounding said flow tube center portion and said balance bar with said balance bar being substantially parallel to and surrounding said flow tube center portion; a first and a second end of said case; an opening in each of said case ends for receiving said flow tube extension that project beyond said case ends; said opening in said case ends is coaxial with a longitudinal axis of said flow tube extension; brace bar means coupling ends of said balance bar to said flow tube; case connect link means having a first end coupled to said balance bar and having a second end coupled to an inner wall of said case; said case connect link means is effective to inhibit the movement of said brace bar and said balance bar ends in a direction perpendicular to said longitudinal axis of said flow tube in said driven plane; a cone connect means having an outer circumference coupled to said case end and having a circular opening coaxial with said flow tube extension for sealably receiving said flow tube extension; and said cone connect means being axially positioned between a terminus of said flow tube extension and said case connect link means.
