Abstract
A Coriolis flow sensor including a loop-shaped Coriolis tube mounted in a housing with two ends lying next to one another, the ends being fixed in a fixation element, while the portion of the tube located between the ends lies free from the housing, which flow sensor includes an excitation element for causing the tube to oscillate about an excitation axis as well as a detection element for detecting displacements of portions of the tube during operation. The tube is connected through the fixation element to a balancing member, the assembly of the balancing member and the tube being resiliently arranged with respect to the housing, while the excitation element are arranged to rotate the tube and the balancing member with counter-phase about the excitation axis.
