Abstract:
A Coriolis flowmeter adapted to receive a material flow at an inlet and to extend said material flow through a flow tube to an outlet of said Coriolis flowmeter; said Coriolis flowmeter also includes:a balance bar positioned parallel to said flow tube; brace bars coupling ends of said balance bar to said flow tube; a driver that vibrates said flow tube and balance bar in phase opposition; pick off means coupled to said balance bar and to said flow tube to generate signals representing the Coriolis response of said vibrating flow tube with material now; a first end portion of said balance bar extending axially inward from a first one of said brace bars towards a mid-portion of said balance bar; a second end portion of said balance bar extending axially inward from a second one of said brace bars towards said mid-portion of said balance bar; and an axial mid-portion of said balance bar having a compliance that enables said balance bar to expand and contract axially without imparting any axial stress to said now tube.
