Patent ID: 7363689

Claim:
A method for producing a connection of a metal cap to a supporting arrangement of a vibration-type sensor for a fluid, the sensor being suitable for use in a pipeline at least temporarily containing the fluid flowing therethrough, comprising the steps of: providing at least one curved measuring tube that vibrates during operation and guides the fluid; providing a metal housing enclosing the at least one measuring tube, the housing having the supporting arrangement of metal, in which the at least one 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, and having the metal cap composed of a first cap half and a second cap half for covering the measuring tube segment, or measuring tube segments, an edge of the first cap half including a first edge portion, a second edge portion, a third edge portion, and a fourth edge portion, and an edge of the second cap half including a fifth edge portion, a sixth edge portion, a seventh edge portion, and an eighth edge portion; connecting the first, second and third edge portions, respectively the fifth, sixth and seventh edge portions, continuously to the supporting arrangement; and connecting the fourth and the eighth edge portions continuously to one another; and cutting a segment in such a manner out of a dish-shaped intermediate having a surrounding edge bead formed thereon, that the first edge portion and the fourth edge portion, respectively the fifth edge portion and the eighth edge portion, and, at the edge bead, the second edge portion and the sixth edge portion, respectively the third edge portion and the seventh edge portion, are created, wherein: a first of these segments is placed on the supporting arrangement, covering a first half of the measuring tube part, or measuring tube parts, a second of these segments is placed on the supporting arrangement, covering a second half of the measuring tube part, or measuring tube parts, in such a manner that the fourth and the eighth edge portions lie opposite one another, the first, the second, the third, the fifth, the sixth and the seventh edge portions are welded completely to the supporting arrangement, and the fourth edge portion is welded completely to the eighth edge portion.
