Abstract: An apparatus for determining or monitoring a process variable of a medium in a pipeline, which has a predetermined inner cross section, comprising a sensor and a T-shaped adapter. The adapter has a first portion and a second portion arranged essentially perpendicular to the first portion. The first portion has essentially the same inner cross section as the pipeline and the sensor is so arranged in the second portion that the end face of the sensor facing the medium is flush with the inner surface of the first portion of the adapter.

Abstract: A system for determining and/or monitoring a process variable of a medium in a container, comprising a sensor module with an oscillatable unit, which is arranged in such a manner in the container that the oscillatable unit extends to a defined immersion depth in the medium, or that the oscillatable unit is placed at the height of the predetermined fill level, a tubular extension and/or a temperature reduction unit of a defined length, a contacting module and an electronics module, composed of an exciter/receiving unit, which excites the oscillatable unit to execute oscillations and receives the oscillations of the oscillatable unit. Two electrical coupling paths are associated with the electronics module, and a control/evaluation unit, which based on at least one oscillation variable of the oscillations or based on a change of an oscillation variable of the oscillations, provides information concerning the process variable or the reaching of the predetermined fill level. The sensor module and the electronics module are either electrically connected directly with one another, wherein one of the two electrical coupling paths is activated, or wherein the sensor module and the electronics module are indirectly electrically connected with one another via the contacting module, and wherein both coupling paths are activated.
