Abstract

A process monitoring device includes: a measuring tube arrangement including a measuring tube; a receptacle module including a receptacle, wherein the measuring tube module is insertable into the receptacle and releasably mechanically connectable to the receptacle module; and a system for biotechnological applications, wherein the system includes a housing with a wall delimiting an interior, the wall having a cover with an opening, wherein the receptacle extends through the opening into the interior in a receiving direction, wherein the receptacle module is arranged in the opening that the receiving direction has a vector component opposite to the direction of gravity, such that a dead volume in the measuring tube and/or in a distributor piece which is attached to the measuring tube, when the measuring tube module is empty, is less than 20%.

First claim

The invention claimed is:

1 . A process monitoring device, comprising:
a measuring tube module comprising at least one measuring tube configured to enable a medium to flow therethrough; a receptacle module comprising a receptacle module body, which at least partially delimits a receptacle, wherein the measuring tube module is adapted to be introduced into the receptacle, and wherein the measuring tube module is releasably mechanically connectable to the receptacle module; and a system comprising a housing, wherein the housing includes a housing wall, which is made of sheet metal and delimits a housing interior, wherein the housing wall includes a cover, which includes a cover opening, wherein the receptacle module, in particular the receptacle, extends through the cover opening into the housing interior, wherein the receptacle extends in a receiving direction, wherein the receptacle module is arranged in the cover opening such that the receiving direction includes a vectorial component having a direction opposite to the direction of gravity, wherein the receptacle module is arranged in the cover opening such that a dead volume in the at least one measuring tube and/or in a distributor piece attached to the at least one measuring tube, when the measuring tube module is empty, is less than 20%, wherein the receptacle module includes a portion, which is outside the housing interior, wherein the receptacle module, in the portion, includes a circumferential shoulder, which includes a shoulder surface, wherein the cover includes a cover surface, wherein the shoulder surface and the cover surface face each other, wherein an inclination body is secured between the shoulder surface and the cover surface, and wherein the inclination body is wedge-shaped, including an acute angle.

2 . The process monitoring device of claim 1 , wherein the dead volume is less than 5%.

3 . The process monitoring device of claim 1 , wherein:
the inclination body includes a first lateral surface in which a first lateral surface plane extends; the inclination body includes a second lateral surface in which a second lateral surface plane extends; the first lateral surface plane and the second lateral surface plane are at a first angle of 0.1° to 15°.

4 . The process monitoring device of claim 3 , wherein the first angle is 0.5° to 7°.

5 . The process monitoring device of claim 1 , wherein the inclination body includes an inclination body opening,
wherein the receptacle module extends at least partially through the inclination body opening.

6 . The process monitoring device of claim 1 , wherein the inclination body is configured as a seal to enable sealing the housing interior against external liquids.

7 . The process monitoring device of claim 6 , wherein the inclination body is made of an EPDM material.

8 . The process monitoring device of claim 1 , wherein the inclination body includes an inclination body recess configured to accept seal,
wherein the seal is disposed in the inclination body recess.

9 . The process monitoring device of claim 1 , wherein a disk-shaped seal is disposed between the inclination body and the cover surface.

10 . The process monitoring device of claim 1 , wherein the inclination body in a longitudinal section assumes a basic shape of a right trapezoid.

11 . The process monitoring device of claim 1 , wherein the inclination body has a rectangular basic shape, including a rectangular cutout defining the inclination opening.

12 . The process monitoring device of claim 1 , wherein the receptacle module comprises a fastening arrangement, which is disposed in the housing interior,
wherein the fastening arrangement is configured to connect the receptacle module to the cover mechanically.

13 . The process monitoring device of claim 1 , wherein the system comprises a bioreactor or a subsystem configured for chromatographic purification processes.

14 . The process monitoring device of claim 1 , wherein:
the measuring tube module includes a first vibration exciting component of at least one vibration exciter, which is configured to excite vibrations in the at least one measuring tube of the measuring tube module; the measuring tube module includes a first vibration sensor component of at least one vibration sensor, which is configured to detect the vibrations of the at least one measuring tube; the receptacle module includes a second vibration exciting component of the at least one vibration exciter; and the receptacle module includes a second vibration sensor component of the at least one vibration sensor.

15 . The process monitoring device of claim 1 , wherein at least the measuring tube module and the receptacle module form a modular Coriolis flow measuring device.

16 . A process monitoring device, comprising:
a measuring tube module comprising at least one measuring tube configured to enable a medium to flow therethrough; a receptacle module comprising a receptacle module body, which at least partially delimits a receptacle, wherein the measuring tube module is adapted to be introduced into the receptacle, and wherein the measuring tube module is releasably mechanically connectable to the receptacle module; and a system comprising a housing, wherein the housing includes a housing wall, which is made of sheet metal and delimits a housing interior, wherein:
the housing wall includes a cover, which includes a cover opening;
the receptacle module, in particular the receptacle, extends through the cover opening into the housing interior;
the receptacle extends in a receiving direction;
the receptacle module is arranged in the cover opening such that the receiving direction includes a vectorial component having a direction opposite to the direction of gravity;
the receptacle module is arranged in the cover opening such that a dead volume in the at least one measuring tube and/or in a distributor piece attached to the at least one measuring tube, when the measuring tube module is empty, is less than 20%;
the receptacle module includes a portion, which is outside the housing interior;
the receptacle module, in the portion, includes a circumferential shoulder, which includes a shoulder surface;
the cover includes a cover surface;
