ABSTRACT:
A Coriolis type flowmeter is described having 12 parallel flow tubes joined to a hub whose geometry is chosen to also perform the function of an inlet and outlet manifold. Plates are provided to interconnect and average the motion of the flow tubes as well as providing a platform for sensing Coriolis induced motion and inducing harmonic oscillations. Because of its symmetric geometry and balanced characteristics, the flowmeter is insensitive to vibration in any axis perpendicular to the axial axis of symmetry.
