Coriolis mass flowmeter

摘要

A Coriolis mass flowmeter (1) having at least one curved measuring tube (2), at least one oscillation generator (3), at least one oscillation sensor (4), at least one measuring device electronics (5) and a housing (6). To provide the housing (6) with increased pressure resistance, in particular against external positive pressure, the housing (6) has a first housing shell and a second housing shell, the first housing shell and the second housing shell completely surrounding the measuring tube (2) so as to form at least a first pressure-resistant hollow space around the measuring tube (2), and the first housing shell and the second housing shell forming a bridge (13) between the inlet (10) and the outlet (11) of the measuring tube (2).

主权项

1. Coriolis mass flowmeter, comprising:
at least one curved measuring tube having an inlet and an outlet, at least one oscillation generator arranged for vibrating said at least one curved measuring tube, at least one oscillation sensor arranged for detecting vibration said of at least one curved measuring tube, at least one measuring device electronics for measuring vibration detected by said at least one oscillation sensor, and a housing enclosing at least said at least one curved measuring tube, wherein the housing comprises a first housing shell and a second housing shell, wherein the first housing shell and the second housing shell completely surround the at least one curved measuring tube in a manner forming at least a first pressure-resistant hollow space around at least the at least one curved measuring tube, wherein the first housing shell and the second housing shell are joined together at a joining plane that runs parallel to a plane formed by a central measuring tube axis, wherein the first housing shell and the second housing shell together form a bridge between the inlet and the outlet of the at least one curved measuring tube, and wherein the bridge forms a solid region that extends in said joining plane both across the housing between the inlet and outlet of the measuring tube and at least partially into a region of an imaginary direct connection line between the inlet and outlet of the measuring tube.
