This sensor ( 1 ), for a fluid and suitable for use in a pipeline at least temporarily containing the fluid flowing therethrough, has at least one curved measuring tube ( 4, 5 ), which vibrates during operation and guides the fluid, and a housing enclosing the measuring tube. The housing is composed of a metal cap ( 7 ) of two cap halves ( 71, 72 ) and a supporting tube ( 6 ), in which the measuring tube is held at its inlet and outlet ends in a manner such that the tube can oscillate, and out of which a measuring tube segment protrudes sideways. Each cap half has an edge ( 73; 74 ) with, in each case, four edge portions ( 731, 732, 733, 734; 741, 742, 743, 744 ). The edge portions ( 731; 741 ) are straight, the edge portions ( 732, 733; 742, 743 ) are curved, and the edge portions ( 734; 744 ) have the shape of circular arcs. The edge portions ( 731, 732, 733; 741, 742, 743 ) are welded continuously to the supporting tube ( 6 ) and the edge portions ( 734; 744 ) are welded continuously to one another. The cap halves ( 71, 72 ) are cut out of a dish-shaped intermediate ( 70 ) having a formed, surrounding edge bead ( 701 ), provided with the shape of a quarter-torus by metal spinning. |
