Abstract
The present invention is directed to a Coriolis mass flowmeter having first and second generally parallel flowtubes which each extend between an inlet manifold and an outlet manifold and comprise respective first and second centerlines that lie in corresponding parallel first and second planes, at least one force driver for vibrating the first and second flowtubes in a natural mode of vibration and at least one motion sensor for detecting the vibrating motion of the flowtubes. In particular, the invention comprises at least one brace bar for decoupling extraneous modes of vibration in the flowtubes from the desired driven and Coriolis modes of vibration. The brace bar includes a first stiffening member having a first opening through which the first flowtube is received and secured; a second stiffening member having a second opening though which the second flowtube is received and secured; and at least one bridge component which is connected to the first stiffening member proximate the first plane and the second stiffening member proximate the second plane.
