Description

Gas-Aräometer, bei welchem der von Gas umgebene Schwimmer von einem Flüssigkeitsschwimmer getragen wird. Die bekannten Gas-Aräometer, bei denen der vom Gas umgebene Schwimmer von einem Flüssigkeitsschwimmer getragen wird, haben den Nachteil, daß bei wechselnden Drücken und Temperaturen des Gases erhebliche Meßfehler entstehen, weil der hohle, mit Luft gefüllte, von dem Gas umgebene Schwimmer sein Gewicht unverändert beibehält und demgemäß seine Gleichgewichtslage bei Druck-und Temperaturschwankungen des ihn tragenden Meßgases ändert. Die auf diese Weise entstehenden Fehler sind sehr erheblich.Gas hydrometer, in which the swimmer surrounded by gas is Liquid float is worn. The well-known gas hydrometers where the a float surrounded by gas is carried by a liquid float the disadvantage that with changing pressures and temperatures of the gas considerable Measurement errors arise because of the hollow, air-filled float surrounded by the gas maintains its weight unchanged and accordingly its position of equilibrium under pressure and Changes in temperature of the measuring gas carrying it. The ones that arise in this way Errors are very significant.

Gegenstand der Erfindung ist nun ein Gas-Aräometer, bei dem diese l@Ießfehler dadurch vermieden werden, daß der Innenraum des vom Gas umgebenen Schwimmers mit der Außenluft `bzw. mit dem die Schreibvorrichtung enthaltenden Raum in Verbindung steht, uni die durch Temperatur- oder Druckschwankungen hervorgerufenen Volumenänderungen zu ermöglichen, also das Schwimmergewicht im gleichen Verhältnis zu verändern, wie das spezifische Gasgewicht durch die Druck- oder Temperaturschwankungen wechselt.The invention now relates to a gas hydrometer in which this L @ Ieß Fehler be avoided by the fact that the interior of the float surrounded by the gas with the outside air `resp. in communication with the space containing the writing device stands, uni the volume changes caused by temperature or pressure fluctuations to make it possible to change the swimmer's weight in the same proportion as the specific gas weight changes due to pressure or temperature fluctuations.

Die Zeichnung veranschaulicht eine beispielsweise Ausführungsform eines solchen Gas Aräometers gemäß der Erfindung.The drawing illustrates an example embodiment of such a gas hydrometer according to the invention.

Der zum Gasdurchfluß dienende Behälter a enthält einen hohlen Schwimmer b, der durch eine Stange d mit einem Flüssigkeitsschwimmer e verbunden ist. Letzterer schwimmt in einem Flüssigkeitsbehälter f und ist unten durch ein Gewicht ; beschwert, das die aufrechte Lage des Schwimmersystems gewährleistet. Auf dem Schwimimer b sitzt ein Rohr, das eine Schreibvorrichtung trägt, die sich in einem besonderen Raumei befindet. Unten mündet das Rohr in -das Innere des Schwimmers b, oben in den Raum der Schreibvorrichtung, so daß beide Räume miteinander verbunden sind. Der Raum i steht mittels einer Sieböffnung L mit der Außenluft in Verbindung.The container a used for gas flow contains a hollow float b which is connected by a rod d to a liquid float e. The latter floats in a liquid container f and is down by a weight; weighted, which ensures the upright position of the float system. On the bucket b sits a tube that carries a writing device that is in a special room egg. At the bottom the tube opens into the interior of the float b, and at the top into the space of the writing device, so that the two spaces are connected to one another. The room i is connected to the outside air by means of a sieve opening L.

Die Temperaturschwankungen der Meßgase teilen sich schnell durch die dünne Schwimmerwandung der Luft im Schwimmer b mit, deren dadurch bedingter Volumenausgleich durch das Rohr k hindurch erfolgt. In dem Raum i herrscht derselbe Druck wie in dem Behälter a, da beide durch das Loch für das Rohr k in der oberen Behälterwand verbunden sind. Demgemäß findet auch der durch Druckschwankungen des Meßgases bedingte Volumenausgleich des Schwimmer inhaltes statt.The temperature fluctuations of the measurement gases are quickly divided by the thin float wall of the air in float b with the resulting volume compensation takes place through the tube k. The same pressure prevails in room i as in the container a, as both through the hole for the tube k in the upper container wall are connected. Accordingly, the pressure fluctuations in the measuring gas also take place Volume compensation of the float content takes place.
