Beschreibung description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1. The invention relates to a device according to the preamble of claim 1.

In solchen Vorrichtungen wird das Meßrohr stark druckbelastet und kann daher während des Betriebs brechen. In such devices, the measuring tube is subjected to high pressure and can therefore break during operation.

Aufgabe der Erfindung ist es, einen solchen Bruch nach Möglichkeit zu vermeiden. The object of the invention is to avoid such a break if possible.

Die Lösung dieser Aufgabe ist in Anspruch 1 angegeben. The solution to this problem is specified in claim 1.

Zur Lösung der Aufgabe haben sich besonders die Ausführungen gemäß Anspruch 2 und 3 bewährt. To achieve the object, the designs according to claims 2 and 3 have proven particularly useful.

Die Erfindung wird im folgenden an einem Ausführungsbeispiel unter Hinweis auf die beigefügte Zeichnung erläutert. The invention is explained below using an exemplary embodiment with reference to the accompanying drawings.

In der Zeichnung ist ein Meßrohr in einem Trägerrohr mit den zugehörigen, zur Abstützung dienenden Ringen im Achsschnitt dargestellt. In the drawing, a measuring tube is shown in a carrier tube with the associated support rings in an axial section.

Ein Meßrohr 2 aus Keramik, Glas, Metall oder Kunststoff ist in ein Trägerrohr 4 aus Metall eingesetzt. Zwischen den Enden 6, 8 des Meßrohrs 2 und den Enden 10, 12 des Trägerrohrs 4 befinden sich Ringe 14, 16 aus Keramik, Glas, Metall oder Kunststoff, die an dem Meßrohr 2 und dem Trägerrohr 4 durch elastische Dichtungsringe 18, 20, 22, 24 abgestützt sind. A measuring tube 2 made of ceramic, glass, metal or plastic is inserted into a carrier tube 4 made of metal. Between the ends 6, 8 of the measuring tube 2 and the ends 10, 12 of the carrier tube 4 are rings 14, 16 made of ceramic, glass, metal or plastic, which on the measuring tube 2 and the carrier tube 4 by elastic sealing rings 18, 20, 22nd , 24 are supported.

Zur Aufnahme der Ringe 18, 20, 22, 24 befinden sich in den Enden 6, 8 des Meßrohrs 2 und den Enden 10, 12 des Trägerrohrs 4 axial offene Ringaus-nehmungen 26, 28, 30, 32. For receiving the rings 18, 20, 22, 24 there are axially open ring recesses 26, 28, 30, 32 in the ends 6, 8 of the measuring tube 2 and the ends 10, 12 of the carrier tube 4.

Die Dichtungsringe 18,20,22,24 liegen in axial inneren Ringschultern 34, 36, 38, 40, die in den radial inneren und radial äußeren, axial nach innen weisenden Kantenbereichen der Ringe 14, 16 eingeformt sind. The sealing rings 18, 20, 22, 24 lie in the axially inner ring shoulders 34, 36, 38, 40, which are formed in the radially inner and radially outer, axially inward-facing edge regions of the rings 14, 16.
