The vortex flowmeter has wall (1) forming medium chamber (2) having jam element with pressure sensor for detecting pressure of adjacent medium. An optical fiber (3) is fed by pressure resistant fiber duct (4) in wall into outer space (5). The fiber duct has fiber channel (6) between contact surfaces of sealing elements (7,9). The sealing element (9) fed in guide (11) formed in wall is pressed against sealing element (7) by actuating element (12) in sealing state of fiber duct such that fiber is clamped between contact surfaces and fiber channel is closed by contact surfaces. |
