Abstract

A Coriolis flow meter, includes: a measuring tube arrangement with at least one measuring tube and a fixing body arrangement; at least one oscillation exciter and at least one oscillation sensor; a support apparatus with seat and fixing apparatus, wherein the fixing apparatus has at least one swingable fixing element, wherein the fixing apparatus is adapted to connect the measuring tube arrangement, for example, the at least one measuring tube, via the fixing body arrangement mechanically releasably with the support apparatus body, wherein the at least one fixing element is adapted in the case of connecting the measuring tube arrangement with the support apparatus body to exert a bending force on the fixing body arrangement for elastically bending the fixing body arrangement.

First claim

The invention claimed is:

1 . A Coriolis flow meter, comprising:
a measuring tube arrangement including at least one measuring tube, which is configured to be flowed through by a medium, and a fixing body arrangement, which is disposed on the at least one measuring tube; at least one oscillation exciter, which is adapted to excite the at least one measuring tube to execute oscillations, wherein the at least one oscillation exciter includes at least two oscillation exciter components, wherein the at least two oscillation exciter components comprise at least one exciter magnet and/or exciter coil, and wherein at least one of the at least two oscillation exciter components is arranged on the measuring tube arrangement; at least one oscillation sensor, which is adapted to register oscillations of the at least one measuring tube, wherein the at least one oscillation sensor includes at least two oscillation sensor components, wherein the at least two oscillation sensor components comprise at least one sensor magnet and/or sensor coil, and wherein at least one of the at least two oscillation sensor components is arranged on the measuring tube arrangement; a support apparatus comprising a support apparatus body, a seat and the at least one sensor coil and exciter coil, wherein the measuring tube arrangement is arrangeable in the seat and connectable mechanically releasably with the support apparatus body, wherein the support apparatus includes a fixing apparatus, which is configured to secure the measuring tube arrangement in the seat, wherein the fixing apparatus includes at least one fixing element, wherein the fixing apparatus is configured to connect the measuring tube arrangement via the fixing body arrangement mechanically releasably to the support apparatus body, wherein the at least one fixing element is adapted to exert a bending force on the fixing body arrangement as to effect an elastic bending the fixing body arrangement.

2 . The Coriolis flow meter claim 1 , wherein in a secured state the bending force has at least one force component pointing in a longitudinal direction of the seat.

3 . The Coriolis flow meter of claim 1 , wherein the support apparatus body includes a bearing area in the seat adapted for the fixing body arrangement,
wherein the fixing body arrangement includes a first face, wherein the first face faces the at least one oscillation exciter component, and wherein in a secured state the fixing body arrangement lies with the first face on the bearing area.

4 . The Coriolis flow meter of claim 1 , wherein the seat is bounded transversely to a longitudinal direction thereof by a support apparatus wall, wherein at least one step is formed in the support apparatus wall, and wherein the at least one step comprises the bearing area.

5 . The Coriolis flow meter of claim 4 , wherein an offset body is arranged between the at least one step and the fixing body arrangement.

6 . The Coriolis flow meter of claim 1 , wherein:
the fixing body arrangement includes on a first face a first area and a second area, wherein the second area lies in a plane; the first face faces the at least one oscillation exciter component; the first area and the second area are arranged offset from each other in a longitudinal direction of the measuring tube arrangement; the support apparatus body includes in the seat an essentially planar bearing area adapted for the fixing body arrangement; and in a secured state, the first area rests on the bearing area and the fixing body arrangement is bent by the at least one fixing element such that the second area is shifted in the longitudinal direction of the measuring tube arrangement offset from the plane.

7 . The Coriolis flow meter of claim 6 , wherein the seat consists of exactly one essentially planar bearing area adapted for the fixing body arrangement.

8 . The Coriolis flow meter of claim 6 , wherein the first area is disposed in a longitudinal direction of the seat at an offset relative to the second area, wherein the offset is greater than 0.05 millimeter (mm) and less or equal to 1 mm.

9 . The Coriolis flow meter of claim 8 , wherein the longitudinal direction of the seat is in an installation direction of the measuring tube arrangement.

10 . The Coriolis flow meter of claim 8 , wherein the offset is greater than 0.15 and less than or equal to 0.25 mm.

11 . The Coriolis flow meter of claim 8 , wherein between the first area and the second area a second step is disposed, which forms the offset.

12 . The Coriolis flow meter of claim 1 , wherein the at least one of the at least two oscillation exciter components arranged on the measuring tube arrangement is the at least one exciter magnet, and wherein at least one of the at least two oscillation sensor components arranged on the measuring tube arrangement is the at least one sensor magnet.

13 . The Coriolis flow meter of claim 1 , wherein the fixing element is rotatable or swingable.
