Process monitoring device

A process monitoring device, comprising:

• a measuring tube module comprising at least one measuring tube configured to enable a medium to flow therethrough, wherein the measuring tube module includes a first vibration exciting component of at least one vibration exciter configured to excite vibrations in the at least one measuring tube, and wherein the measuring tube module includes a first vibration sensor component of at least one vibration sensor configured to detect the vibrations of the at least one measuring tube;
• a receptacle module, including a receptacle, wherein:
• the measuring tube module and the receptacle module are configured to enable the measuring tube module to be replaceably inserted into the receptacle of the receptacle module,
• the measuring tube module is configured to be mechanically separably connected to the receptacle module,
• 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;
• and
• an installation for a biotechnological process application, wherein:
• the system installation includes bioreactor vessel disposed within a cabinet,
• the cabinet includes a cabinet wall, which delimits a cabinet interior, and
• the cabinet wall includes a cover, which includes an opening,
• wherein the receptacle of the receptacle module extends through the opening into the cabinet interior of the installation, wherein the opening is configured to enable the measuring tube module to be replaceably inserted directly into the receptacle of the receptacle module.
