an dessen unterem Ende der hydrostatische Druck herrscht,■ und durch das ein Gas, insbesondere Stickstoff, strömt, und mittels eines Organs, das den Gasdruck an einera von dem unteren Rohrende entfernten Ort mißt,at the lower end of which there is the hydrostatic pressure, ■ and through which a gas, in particular nitrogen, flows, and by means of an organ which measures the gas pressure at a location remote from the lower end of the pipe,
Bei bekannten Vorrichtungen dieser Art ragt dos untere Rohrende in das Medium. Das Rohrende kann infolgedessen Veränderungen unterliegen, sei es, daß es allmählich zuwächst, sei es, daß es korrodiert. Auch kann in pevnLssen Fällen durch das Gas das Medium verändert v/erden.In known devices of this type dos lower protrudes End of the pipe in the medium. As a result, the pipe end can be subject to changes, be it that it gradually grows closed, be it that it corrodes. The gas can also change the medium in any eventuality.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnte Vorrichtung derart auszubilden, daß Veränderungen des Rohrendes und/oder des Mediums nicht auftreten.The invention is based on the object of designing the device mentioned at the beginning in such a way that changes of the pipe end and / or the medium do not occur.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sich das untere Rohrende innerhalb einer Flüssigkeit befindet, die mit dem Medium in Verbindung steht, das Rohrende schützt und/oder unerwünschte Veränderungen des Mediums bei Beaufschlagung mit dem Gas verhindert.This object is achieved according to the invention in that the lower end of the pipe is located within a liquid, which is in contact with the medium, protects the pipe end and / or undesired changes in the medium prevented when exposed to the gas.
Eine erste AusführungEfform der Erfindung ist derart ausgebildet, daß die Flüssigkeit, aus einem zweiten Rohr austretend, insbesondere langsam das Ende des ersten Rohres umspült, wobei es zweckmäßig ist, wenn das zweite Rohr das erste Rohr mit Abstand umgibt.A first embodiment of the invention is designed in such a way that that the liquid emerging from a second tube, in particular slowly the end of the first tube washed around, it is useful if the second tube surrounds the first tube at a distance.
Besteht die Gefahr, daß das Gas das Medium austrocknet, kann das Gas mit dem Dampf des Mediums angereichert werden. Schließlich kann man auch das Rohrende kühlen, um Reaktionen soweit wie möglich zu vermeiden.If there is a risk that the gas will dry out the medium, the gas can be enriched with the vapor of the medium. Finally, the end of the pipe can also be cooled in order to avoid reactions as far as possible.
Bei einer zweiten Ausführungsform der Erfindung ragt das örste Rohr in einen Behälter mit der Flüssigkeit, die über ein drittes Rohr mit dem Medium verbunden ist, wobei in denIn a second embodiment of the invention, the örste tube protrudes into a container with the liquid above a third pipe is connected to the medium, with the

behälter die !Flüssigkeit insbesondere langsam strömt.the liquid flows particularly slowly.
Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung, in deren Fig. 1 das Rohrende der ersten Ausführungsforrc und in Fig.. 2 die zweite Ausführungsform scliematisch dargestellt sind.Further details of the invention emerge from the drawing, in which Fig. 1 shows the pipe end of the first Ausführungsforrc and in Fig. 2 the second embodiment is shown schematically.
In Fig. 1 ist 'mit 1 ein Rohr bezeichnet, durch das ein Gas 2 langsam in eine flüssigkeit 3 eingeleitet wird. Des Rohr 1 ist von einem zweiten Rohr 4 umgeben. Durch den Zwischenraum 5 zwischen den beiden Rohren 1 und 4 strömt eine Schutzflüssigkeit 6 in die Flüssigkeit 3· Diese Flüssigkeit 6 vermeidet Je nach den Verhältnissen eine Zerstörung des Rohres 1 bzw. eine Veränderung der Flüssigkeit 3· Der Druck des Gases in dem Rohr 1, der im Abstand von dem Rohrende gemessen wird, ist praktisch gleich dem Druck der Flüssigkeit 3 im Bereich des Rohrendes. In FIG. 1, 1 denotes a pipe through which a gas 2 is slowly introduced into a liquid 3 . The tube 1 is surrounded by a second tube 4 . A protective liquid 6 flows into the liquid 3 through the space 5 between the two tubes 1 and 4 This liquid 6 avoids, depending on the circumstances, a destruction of the tube 1 or a change in the liquid 3 The pressure of the gas in the tube 1, measured at a distance from the pipe end, is practically equal to the pressure of the liquid 3 in the region of the pipe end.
In Fig. 2 ist eine Ausführungsform dargestellt, bei der mit einer kommunizierenden Röhre 7 gearbeitet wird. Diese taucht in'einen Behälter 8 ein, der das Medium 3» z.B. flüssigen Zement, enthält. Das andere Ende des Rohres 7 befindet sich in einem Gefäß 9, das eine neutrale" Flüssigkeit 6 enthält. Außerdem ragt in das Gefäß 9 das das Gas führende Rohr 1. Der Druck des Gases entspricht dem Druck am Ende des Rohres 1 und praktisch dem Druck an dem in . den BehälterVragende Ende des Rohres 7· Um zu verhindern, daß über das Rohr 7 das Medium 3 in das Gefäß 9 strömt, tropft aus einem Behälter 10 die neutrale Flüssigkeit 6 in das Gefäß 9.In FIG. 2, an embodiment is shown in which a communicating tube 7 is used. This is immersed in a container 8 which contains the medium 3, for example liquid cement. The other end of the pipe 7 is located in a vessel 9 which contains a neutral liquid 6. In addition, the pipe 1 carrying the gas protrudes into the vessel 9. The pressure of the gas corresponds to the pressure at the end of the pipe 1 and practically corresponds to the pressure at the end of the tube 7 protruding into the container. In order to prevent the medium 3 from flowing through the tube 7 into the vessel 9, the neutral liquid 6 drips from a container 10 into the vessel 9.
