Abstract
The invention relates to a level meter with two oscillating bodies (2, 3) positioned one inside the other. An equalizing body (5) is positioned in the interior (32) of the inside oscillating body (2). The equalizing body (5) exhibits a section (52) that is at least in part elastic, such that the outer diameter (ds*) of the elastic section in relaxed condition is greater than the inner diameter (dgi) of the interior (32). This provides a good coupling and, at the same time, protection against displacement for the equalizing body (5) relative to the inside oscillating body (3). For supplemental adjustment of the equalizing body (5), the latter is provided with an outside thread (51), which engages with an inside thread (33) belonging to the interior (32). A slot (52) for adjusting the equalizing body (5) is accessible via an access opening (6); the access hole (6) runs in the rearward direction, through the individual components of the level meter (1), including the drive and/or receiving device (7).
