    Abstract: An apparatus for ascertaining and/or monitoring a process variable, especially density of a medium. The apparatus includes: an exciting/receiving unit, which excites a mechanically oscillatable unit to execute mechanical oscillations and which receives the mechanical oscillations; an electronics unit, which applies to the exciting/receiving unit an electrical, exciter signal, and which obtains from the exciting/receiving unit an electrical, received signal.

The contractile hose fits into an annular clamping gap or nip, whose wall bears saw tooth serrations, the saw tooth serrated areas being so arranged that their teeth are radially opposite each other and arranged in pairs each at the same level. The outer saw tooth serrated area is located on a compression sleeve, which is radially pressed to join it with the hose end section surrounded by it.
