Abstract

A fluid level indicator has a glass tube in a protective tube with connectors at both ends having soft metal or plastic seals to the glass tube and around hollow inlet bolts in elongated holes and is attached to a container to show the level within it.

Description

Flüssigkeitstandanzeiger sind in der Technik bekannt. Sie werden in zahlreichen Einsatzgebieten überall dort verwendet, wo der Pegel von fluiden Medien in geschlossenen Behältern sichtbar gemacht werden muss. Das Prinzip beruht auf einer mit dem Behälter kommunizierenden Röhre, mit Hilfe derer der Flüssigkeitsstand leicht von außen abgelesen werden kann.Liquid level indicators are known in the art. They are used in numerous fields everywhere used where the level of fluid media in closed containers visible must be made. The principle is based on communicating with the container Tube, with the help of which the liquid level easily from the outside can be read.

Der Erfindung liegt zum einen das Problem zugrunde, dass bei an zwei Stellen angeflanschten Flüssigkeits-standanzeigern oftmals Spannungen auftreten, die dadurch bedingt sind, dass die Aufnahmelöcher nicht exakt die Distanz der Verbindungselemente des Anzeigers wiederspiegeln. Dies ist zum Teil durch Fertigungstoleranzen und zum anderen durch Längen-änderungen bedingt durch Tem-peraturschwankungen oder Kraftein-wirkungen im Betrieb zu erklären. Durch verschiebbare Endstücke in dem der Erfindung zugrundeliegenden Flüssigkeitsstandanzeiger werden Toleranzen sowie betriebsbedingte Längenabweichungen kompensiert. Es treten keine Spannungen auf, die die Betriebssicherheit des Anzeigers gefährden könnten.Of the On the one hand the invention is based on the problem that at two Place flanged fluid level indicators often tensions arise because of the fact that the receiving holes not exactly reflect the distance of the fasteners of the indicator. This is partly due to manufacturing tolerances and partly due to changes length due to temperature fluctuations or force effects in the Explain operation. By sliding end pieces in which the invention underlying liquid level indicator Tolerances and operational length deviations compensated. There are no voltages that affect the reliability of the indicator threaten could.

Ein weiteres Problem, welches der Erfindung zugrunde liegt ist, dass bei üblichen Flüssigkeitsstandanzeigern für jede Länge ein eigenständiger Anzeiger gefertigt und auf Lager gehalten werden muss. Durch die mehrteilige Konstruktion der Erfindung ist es möglich mit Hilfe nur einer Baugröße eine Vielzahl von verschiedenen Längen durch Wahl des ent-sprechenden Schauglases und Schutz-rohres zu realisieren.One Another problem underlying the invention is that at usual Liquid level indicators for every Length one independent Indicator must be made and kept in stock. By the multi-part construction of the invention, it is possible with the help of only one size Variety of different lengths by choosing the appropriate sight glass and protective tube realize.

Die Verträglichkeit mit den unter-schiedlichsten fluiden Medien wird durch die Wahl des geeigneten Werk-stoffes für die metallischen Kom-poneten des Anzeigers sowie die Wahl der Weichdichtungen gewährleistet.The compatibility with the most diverse fluid media is by choice suitable material for ensuring the metallic components of the indicator as well as the choice of soft seals.
