Abstract:
1. A mass flowmeter of the Coriolis type, comprising: a sensing tube including a mechanically closed loop in a shape of substantially one full turn, said loop having a main symmetry axis and further including a flexible inlet tube and flexible outlet tube; and excitation means being provided for causing the loop to rotate in an oscillating mode about the main axis of symmetry of the loop, the loop having two closely opposed ends that are connected to first ends of the flexible inlet tube and the flexible outlet tube, the other ends of the inlet tube and outlet tube being connected to a supply/discharge block, which inlet and outlet tubes extend in parallel in the plane of and within the loop, symmetrically with respect to the main symmetry axis, between said first ends and fixation means associated with a frame for fastening them, and which inlet and outlet tubes are connected to one another between said first ends and the fixation means by soldering or welding, whereby the loop is resiliently suspended from the frame by the flexible inlet and outlet tubes, the resulting suspension allowing a movement about two perpendicular axes in the plane of the loop, one for the excitation movement about the main symmetry axis and one for the Coriolis response movement.
