Abstract

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.
