Abstract
A Coriolis mass flow meter includes: a measuring tube for guiding a medium; a support body connected to the measuring tube on the inlet side and on the outlet side; an exciter for exciting bending vibrations of the measuring tube; at least two vibration sensors for detecting vibrations of the measuring tube; and a reinforcing body fastened to a lateral surface of the measuring tube and surrounds the measuring tube, the reinforcing body including, at least in sections, a helical course with a plurality of windings, a distance between two adjacent windings of the reinforcing body being not less than twice, for example, not less than four times or not less than eight times, a material thickness of the reinforcing body in the region of the windings.
Claims22
A Coriolis mass flow meter, comprising:
- an oscillatory first measuring tube configured to convey a medium;
- at least one support body, which is connected to the first measuring tube on an inlet side and on an outlet side of the flow meter;
- at least one exciter operable to excite at least one bending vibration mode of the first measuring tube;
- at least two vibration sensors operable to detect vibrations of the first measuring tube;
- and
- a first reinforcing body, which is attached to a lateral surface of the first measuring tube and surrounds the first measuring tube,
- wherein the first reinforcing body, at least in sections, includes a helical course having a plurality of windings,
- wherein a distance between two adjacent windings of the plurality of windings is not less than twice a material thickness of the first reinforcing body in the corresponding section of the windings.
