Description

Der Erfindung liegt die Aufgabe zugrunde, den Inhalt eines gechlossenen Flüssigkeitsbehälters in einfacher Weise und mit einfachen Mitten zu messen.The invention is based on the object of the content of a closed To measure liquid container in a simple manner and with simple means.

Es ist bereits vorgeschlagen worden, dem zu bemessenden Flüssigkeitsbehälter eine bestimmte Menge Luft zuzuf2hren und dann den sich ergebenden Gesamtdruck des Meßbehältersc und des Flüssigkeitsbehälters mit Hilfe einer manometerartigen Meßcinrichtung zu messen. Derartige Vorrichtungen lassen sich jedoch nich tin Massen preiswert herstellen. Es besteht aber ein dringendes Bedürfnis, Kelinbehälter inhaltlich zu messen, die mit den bisher bekannten Einrichtungen nur ungenau gemessen werden kionnten.It has already been proposed that the liquid container to be measured to supply a certain amount of air and then the resulting total pressure of the Meßbehältersc and the liquid container with the help of a manometer-like measuring device to eat. However, such devices are not inexpensive in bulk produce. But there is an urgent need to close the contents of kelin containers measure that could only be measured imprecisely with the previously known devices.

Das Wesentliche der Erfindung besteht darin, daß in den Behälter, dessen Flüssigkeitsmentge zu messen ist, durch einen Arbeitskoben mit konstanter Kraftquelle Preßluft eingeführt wird, der dann einen veranderlchen Weg zurücklegt, bis der Druck der konstanten Kraftquelle mit dem Luftdruck im Innern des Behälters im Gleichgewicht ist, und daß dieser Weg den Meßwert darstellt, wenn die Wegstrekce in entsprechenden Literzeichen erkennbar gemacht wird.The essence of the invention is that in the container, whose liquid content is to be measured by a working piston with constant Power source compressed air is introduced, which then covers a different path, until the pressure of the constant power source with the air pressure inside the container is in equilibrium, and that this path represents the measured value if the path distance is made recognizable in the corresponding liter characters.

Die Vorrichtung besteht aus einem Zylinder und einem Arbetiskolben, der durch eine starke Druckfeder belastet ist. Die Kolbenstange dient als Maßstab.The device consists of a cylinder and a working piston, which is loaded by a strong compression spring. The piston rod serves as a benchmark.

Nachstehend wird die erfindungsgemäße Vorrichtung in einem Ausführungseispiel an Hand der schematichen Zeichung näher erläutert. vor dem eigentlichen Meßvorgang wird zuerst zur Gewinnung der nötigen Kraftquelle für dei erforderliche Preßluft die Kolbenstange a des Arbeitskolbens b herausgezogen, bis die Druckfeder c vollständig gespannt sit. Eine Feststelleinrichtung geeigneter Art sichert dabei den gespannten Zustand. Die Meßvorrichtung wird dann mit dem Flüssigkeitsbehälter d mit Hilfe eines geeigneten anschlusses verbunden. Nach diesem Anschluß ist zur Messung lediglich die Kolbensperreinrichtung zu lösen, und dann dringt der Arbeitskolben b in den Zylinderraum vor. Der Kolben legt je nach dem Behöterinhalt immer einen unterscheidlichen Weg zurück, bis er zum Stillstand kommt, weil die Kraftquelle konstant ist. Der Kolbenweg wird zweckmäßig inenfhcer Weise durch die Kolbenstange a durch Anbringung von Maßzeichen, die über dem Zylinderdeckel bei gespanntem Kolben betginnen, übersichtlich dargestellt, so daß ohne weiteres bei Litereinteilung der Inhalt ablesbar ist.The device according to the invention is shown below in an exemplary embodiment explained in more detail on the basis of the schematic drawing. before the actual measuring process is first used to generate the necessary power source for the compressed air required the piston rod a of the working piston b is pulled out until the compression spring c is completely excited to sit. A locking device of a suitable type secures the cocked one State. The measuring device is then connected to the liquid container d with the help of a appropriate connection connected. After this connection is only for measurement to release the piston locking device, and then the working piston b penetrates into the Cylinder space in front. The flask always places a different one depending on the contents of the container Way back until it comes to a standstill because the power source is constant. Of the Piston travel is expediently inefhcer way through the piston rod a by attachment of dimensional symbols that start over the cylinder cover when the piston is cocked shown so that the content can be read off easily with the liter division.

Es kann aber auch die Kolbenstange mit einem Zeiger versehen werden, und über dem Zylinderdeckel wird eine festzustellende Maßskala angebracht. Auch ist es möglich, die Kolbenstange mit einem besonderen Meßanzeiger gelenkig zu verbinden.The piston rod can also be provided with a pointer, and a measuring scale to be determined is attached above the cylinder cover. Even it is possible to articulate the piston rod with a special measuring indicator.

Die einfachen Ausstattungsmöglichkeiten einer solchen Vorrichtung gestatten eine preiswerte Massenherstellung, so daß einer allgemeinen Verwendbarket für Kleinbehälter nichts im Wege steht. Die Anschaffungskosten werden durch die damit erreichbare Ausschaltung der flüssigkeitsverschüttung o. dgl. in kurzer Zeit, z. B. bel flüssigen Brennstoffen. Ölen usw. ausgelgichen.The simple equipment options of such a device allow inexpensive mass production so that they are of general use nothing stands in the way for small containers. The acquisition costs are determined by the thus achievable elimination of liquid spills or the like in a short time, z. B. bel liquid fuels. Oils etc. balanced.

An Stelle der Preßluft kann auch dem Behälter Luft entzogen werden. wenn der Arbeitskolben als Kraftquelle eine Zugfeder erhält und diese Vorrichtung in der übrigen Ausführung entsprechend angepaßt wird.Instead of the compressed air, air can also be withdrawn from the container. when the working piston receives a tension spring as a power source and this device in the rest of the design is adapted accordingly.
