Patent ID: 8881605

Claim:
A Coriolis flow sensor, comprising: a loop shaped Coriolis tube mounted in a housing with two ends lying next to one another, the ends being fixed in a tube fixation means, a portion of the tube located between the ends lying free from the housing; excitation means for causing the tube to oscillate about an excitation axis; and detection means for detecting displacements of portions of the tube during operation, wherein the tube through the tube fixation means is connected to a balancing member, an assembly of the balancing member and the tube being resiliently arranged with respect to the housing, the assembly of the balancing member and the tube being suspended relative to the housing by resilient means such that the assembly can rotate about an axis of rotation that is at least substantially parallel to or coincides with the excitation axis of the tube, the excitation means being configured to rotate the tube about the excitation axis in counter-phase with the balancing member.
