Abstract:
A method of forming a Coriolis flowmeter having a flow tube and a balance bar that are adapted, when in use, to be vibrated in a driven plane in phase opposition to generate a Coriolis response in said vibrating flow tube representing information pertaining to material flowing through said vibrating flow tube;said flow tube has a flow tube center portion and a flow tube extension at each end of said flow tube; said method comprising the steps of: surrounding said flow tube and said balance bar with a case with said balance bar being substantially parallel to said flow tube; said case having first and a second ends; including an opening defining a cone connect in each of said case ends for receiving said flow tube extension that project beyond said case ends; sealably coupling said opening in said cone connect to said flow tube extension; coupling ends of said balance bar to said flow tube with brace bar means; coupling said brace bar and said balance bar to an inner wall of said case with case connect link means having first and second ends; forming said Coriolis flowmeter so that a terminus of said flow tube extension that is devoid of attachment to any other structure; and said case connect link means is effective to inhibit movement of said brace bar and said balance bar ends in a direction perpendicular to a longitudinal axis of said flow tube in said driven plane.
