A method is disclosed for producing a connection between a measuring tube and at least one flange, e.g., in the case of a Coriolis mass flowmeter. In order to ensure reliable connection of the components in this case, the measuring tube can be inserted at one end over a portion through a flange bore, such that it projects out of the bore on the other side, and that the projecting end be flared out over the sealing face of the flange.

What is claimed is: 1. A method of producing a connection between a measuring tube and at least one flange with at least one sealing face on one side, comprising: inserting the measuring tube at one end over a portion through a flange bore, such that it projects out of the bore on the other side, a
What is claimed is: 1. A method of producing a connection between a measuring tube and at least one flange with at least one sealing face on one side, comprising: inserting the measuring tube at one end over a portion through a flange bore, such that it projects out of the bore on the other side, and flaring the projecting end out over the sealing face of the flange, wherein the tube portion is firstly inserted through an annular disk, which in turn is welded or brazed firmly to the tube, and is then subsequently pressed into an at most exactly fitting receiving opening in the flange, and then said tube portion is flared round altogether. 2. The method as claimed in claim 1, wherein, during flaring, an expansion tool is firstly introduced into the projecting tube portion, and then the latter is expanded in such a way that it is flared over around the edges of the sealing face. 3. The method as claimed in claim 2, wherein said tube portion is heat-treated for the expansion and flaring process. 4. The method as claimed in claim 1, wherein said tube portion is heat-treated for the expansion and flaring process. 5. The method as claimed in claim 4, wherein said tube portion is pre-heat-treated in such a way that it is soft-annealed. 6. The method as claimed in claim 5, wherein the tube portion to be expanded optionally consists of a different material from the measuring tube itself, and is welded thereto and, after being pushed through the flange, is expanded and flared as described above. 7. The method as claimed in claim 1, wherein the tube portion to be expanded optionally consists of a different material from the measuring tube itself, and is welded thereto and, after being pushed through the flange, is expanded and flared as described above. 8. The method as claimed in claim 7, wherein the tube portion is firstly inserted through an annular disk, which in turn is welded or brazed firmly to the tube, and is then subsequently pressed into an at most exactly fitting receiving opening in the flange, and then said tube portion is flared round altogether. 9. A Coriolis flowmeter having at least one measuring tube which is attached to a flange and is produced by a method comprising: inserting the measuring tube at one end over a portion through a flange bore, such that it projects out of the bore on the other side, and flaring the projecting end out over the sealing face of the flange, wherein the tube portion is firstly inserted through an annular disk, which in turn is welded or brazed firmly to the tube, and is then subsequently pressed into an at most exactly fitting receiving opening in the flange, and then said tube portion is flared round altogether, the measuring tube plus flange being fastenable in a housing or a supporting frame. 10. A method of producing a connection between a measuring tube and at least one flange with at least one sealing face on one side, in the case of a Coriolis mass flowmeter, comprising: inserting the measuring tube at one end over a portion through a flange bore, such that it projects out of the bore on the other side, and flaring the projecting end out, wherein the tube portion is firstly inserted through an annular disk, which in turn is welded or brazed firmly to the tube, and is then subsequently pressed into an at most exactly fitting receiving opening in the flange, and then said tube portion is flared round altogether.
