Abstract
Einrichtung zur Volumenmessung eines gasförmigen Mediums, insbesondere Bio-Gas, in einem Behälter (1), der eine aus einer gasdichten Kunststofffolie bestehende Abdeckung (2) aufweist, wobei an der bei maximaler Befüllung höchsten Stelle auf der Kunststofffolie ein Ausgleichsbehälter (3) angeordnet ist, an den das eine Ende eines mit einem flüssigen Medium gefüllten Schlauchs (4) angeschlossen ist, dessen anderes Ende mit einem Druckaufnehmer (5) verbunden ist, der sich auf der Höhe des Grundes des Behälters (1) befindet, wobei der Ausgleichsbehälter (3) derart ausgebildet ist, dass auf die Flüssigkeitssäule der Atmosphärendruck einwirkt und gleichzeitig ein Flüssigkeitsaustritt verhindert wird und wobei in Steuerabhängigkeit vom Druckaufnehmer (5) eine Auswerteschaltung steht, die ein dem Volumen des gasförmigen Mediums proportionales elektrisches Signal erzeugt.Device for measuring the volume of a gaseous medium, in particular bio-gas, in a container (1) having a cover (2) consisting of a gastight plastic film, wherein at the highest point at maximum filling on the plastic film, a surge tank (3) is arranged to which one end of a tube (4) filled with a liquid medium is connected, the other end of which is connected to a pressure transducer (5) located at the level of the bottom of the container (1), the reservoir (3 ) is designed such that acts on the liquid column of the atmospheric pressure and at the same time a liquid leakage is prevented and wherein in control dependence of the pressure transducer (5) is an evaluation circuit which generates an electrical signal proportional to the volume of the gaseous medium.
Description
Die Erfindung bezieht sich auf eine Einrichtung zur Volumenmessung eines gasförmigen Mediums insbesondere Bio-Gas, über einem Bezugspunkt.The The invention relates to a device for volume measurement of a gaseous Medium, in particular bio-gas, over a reference point.

Patentanmeldung
Am bei vollständiger Befüllung mit Gas höchsten Punkt der Halbkugel liegt eine Kette mit ihrem freien Ende auf, dessen anderes Ende mit einer ortsfesten Gewichtsmessvorrichtung verbunden ist. Die Länge der Kette ist so bemessen, dass bei vollständiger Entleerung des Folienbehälters die Folie auf der ebenen Fläche aufliegt und das freie Ende der Kette keine Berührung mehr mit der Folie hat und die Kette ihr maximales Gewicht hat.At the at more complete filling highest with gas Point of the hemisphere lies a chain with its free end, the other end with a stationary weight measuring device connected is. The length the chain is sized so that when completely emptying the film container the Slide on the flat surface rests and the free end of the chain has no contact with the film and the chain has its maximum weight.
Im Betrieb gibt es immer wieder Probleme, weil die Kette – trotz kleiner Barrieren auf der Folien – Oberfläche aufgrund von nicht vermeidbaren unregelmäßigen Verformungen der Folie beim Füllen (Halbkugel – Biolg) und Entleeren (Folie fällt in sich zusammen) die Kette von der Folie wegrutscht und damit die Volumenbestimmung aus der Kettengewichtsmessung ungenau bis unmöglich wird.in the Operation, there are always problems because the chain - despite small barriers on the films surface due to unavoidable irregular deformations the foil during filling (hemisphere - Biolg) and emptying (foil drops together) the chain slips away from the film and thus the Volume determination from the chain weight measurement is inaccurate to impossible.
Aufgabengemäß soll die neue Einrichtung keine mechanischen Teile aufweisen, in einer explosionsgefährdeten Zone einsetzbar und eine genaue Höhenerfassbarkeit aufweisen und überdies kostengünstig sein.According to the task, the new device have no mechanical parts, in a potentially explosive atmosphere Zone usable and have an accurate height detectability and moreover economical be.
Dies wird mit einer im Anspruch 1 gekennzeichneten Einrichtung erreicht.This is achieved with a device characterized in claim 1.
Vorteilhafte Ausgestaltungen sind den weiteren Ansprüchen zu entnehmen.advantageous Embodiments are given in the further claims.
Anhand eines Ausführungsbeispiels sei die Erfindung näher erleutert.Based an embodiment let the invention be closer erleutert.
