Abstract: A process monitoring device includes: a measuring tube module having at least one measuring tube through which a medium can flow; a receptacle module having a receptacle, wherein the measuring tube module can be inserted into the receptacle, wherein the measuring tube module can be mechanically separably connected to the receptacle module; and a system for biotechnological applications, wherein the system has a housing, wherein the housing has a housing wall, which delimits a housing interior, wherein the housing wall has a cover, wherein the cover has an opening, wherein the receptacle module, in particular the receptacle, extends through the opening into the housing interior.

Abstract: By means of this process it is intended to achieve a high mechanical-geometric accuracy of bent tubes, and it is used for bending a measuring tube for a Coriolis mass flow rate sensor by means of a tube section of a predetermined length and by means of a two-piece press mold, which has been matched to both the measuring tube, which has an inner diameter and an outer diameter, and to the desired shape. To this end, a flexible support body is inserted into the tube section, which is fastened in a first end of the tube section in such a way, that the end is closed, and whose maximum outer diameter is less than the inner diameter of the tube section. The tube section is filled with a liquid which is subsequently permitted to solidify completely. The tube section filled with the support body and the solidified liquid is placed into the opened press mold, the latter is closed and the tube section is bent into the desired shape by this. The press mold is opened and the bent tube section is removed.
