Description

Vorrichtung zum Messen von Gasen. Es ist bereits bekannt, bei Strömungsmessern für Gase mit Drosselstelle (sogenannter Mündungsströmungsmesser) eine Meßflüssigkeif von der überdruck- zur Unterdruckseite durch eine proportional wirkende Drosselstelle hindurchdrücken zu lassen, so daß die hindurchgedrückte Menge ein Mali für die durch die Leitung' hindurchgeströmte Gasmenge ist. Gemäß vorliegen.'der Erfindung wird diese bekannte Meßvorrichtung in der durch den Anspruch gekennzeichneten und nachstehend erläuterten Anordnung als vollkommen in. sich geschlossenes System ohne bewegliche Teile ausgebildet, was besonders dann von Vorteil ist, wenn es sich um aggressive Gase handelt.Device for measuring gases. It is already known in flow meters for gases with a throttle point (so-called orifice flow meter) a measuring liquid from the overpressure to the underpressure side through a proportionally acting throttle point to let push through, so that the pushed through crowd a penalty for the through the line 'is the amount of gas that has flowed through. According to the invention this known measuring device in the characterized by the claim and the arrangement explained below as a completely self-contained system designed without moving parts, which is particularly advantageous when it is aggressive gases are involved.

In der Zeichnung ist A die Kapillare eines Kapomessers, durch deren Durchströmen die Druckdifferenz erzeugt wird, die in dem Differentialmanometer B abgelesen wird. Parallel zu dem Manometer ist die eigentliche Meßvorrichtung geschaltet, die aus einem Vorratsgefäß D für Meßflüssigkeit, z. B. Schwefelsäure, einem kapillaren Steigrohr und der Meßbürette C besteht. Bei einem bestimmten Stand des Manometers drückt dann der zwischen der Gaseingangs- und Gasabgangslei# tung bestehende Überdruck die Meßflüssigkeit tropfenweise in die Bürette. Die Einteilung der Bürette kann direkt für einen bestimmten Druckunterschied so geeicht sein, daß die Skalenteile die Gewichts- bzw. Raummenge des durchgeströmten Gases angebenC Das Vorratsgefäß für die Meßflüssigkeit wird im Verhältnis zu der Meßbürette sehr groß gewählt, damit die Änderung des Flüssigkeitsstandes im Vorratsgefäß nur verschwindenden Einfluß auf die Druckhöhe hat. Auch könnte durch bekannte Vorrichtungen zur Konstanthaltung einer Flüssigkeitshöhe dieser geringe Unterschied im Flüssigkeitsstand vermiedeir. oder auch bei der Eichung der Meßbürette entsprechend berücksichtigt werden.In the drawing, A is the capillary of a capo knife, through the flow of which the pressure difference is generated, which is read in the differential manometer B. The actual measuring device is connected in parallel to the manometer. B. sulfuric acid, a capillary riser and the measuring burette C consists. When the pressure gauge reaches a certain level, the excess pressure existing between the gas inlet and gas outlet lines pushes the measuring liquid drop by drop into the burette. The division of the burette can be calibrated directly for a certain pressure difference so that the scale divisions, the weight or amount of space of the medium passed through gas angebenC The storage vessel for the measuring liquid is very selected large in relation to the measuring burette for the change of the liquid level in the storage vessel only has a negligible influence on the pressure level. Known devices for keeping a liquid level constant could also avoid this slight difference in the liquid level. or can also be taken into account when calibrating the measuring burette.
