Abstract
Einrichtung zur Niveau- oder Füllstandsmessung eines flüssigen Mediums (1) in einem Behälter (2) mit einem, mit einer Flüssigkeit (3) gefüllten, flexiblen ersten Schlauch (4a) der an seinem einen freien Ende einen Druckaufnehmer (5) und an seinem anderen festen Ende einen Ausgleichsbehälter (6) aufweist, wobei das feste Ende des ersten Schlauches (4a) mit der Wand des Behälters (2) an einem Bezugspunkt (7) verbunden ist, wobei der Ausgleichsbehälter (6) derart ausgebildet ist, dass auf die Flüssigkeitssäule der Atmosphärendruck einwirkt und gleichzeitig ein Flüssigkeitsaustritt verhindert wird, wobei über dem flexiblen, mit der Flüssigkeit (3) befüllten ersten Schlauch (4a) ein weiterer flexibler zweiter Schlauch (4b) vorgesehen ist, dessen Innendurchmesser größer als der Außendurchmesser des ersten Schlauches (4a) ist, wobei das freie Ende des zweiten flexiblen Schlauches (4b) geschlossen ist und den Druckaufnehmer (5) aufnimmt und das feste Ende des zweiten Schlauches (4b) mit der Außenwand des Behälters (2) derart verbunden ist, dass ein Druckausgleich...Device for level or level measurement of a liquid medium (1) in a container (2) with a, filled with a liquid (3), flexible first hose (4a) at its one free end a pressure sensor (5) and at the other fixed end has a surge tank (6), wherein the fixed end of the first tube (4a) with the wall of the container (2) at a reference point (7) is connected, wherein the surge tank (6) is formed such that on the liquid column the atmospheric pressure acts and at the same time a liquid outlet is prevented, wherein above the flexible, with the liquid (3) filled first tube (4a), a further flexible second tube (4b) is provided, whose inner diameter is greater than the outer diameter of the first tube (4a) with the free end of the second flexible tube (4b) closed and receiving the pressure transducer (5) and the fixed end of the second tube it (4b) with the outer wall of the container (2) is connected in such a way that a pressure equalization ...
Description
Die Erfindung bezieht sich auf eine Einrichtung zur Niveau- oder Füllstandsmessung eines flüssigen Mediums in einem Behälter.The The invention relates to a device for level or level measurement a liquid Medium in a container.
Eine
solche Einrichtung ist aus der
Diese bekannte Einrichtung benötigt einen zusätzlichen Schwimmer.These known device needed An additional Swimmer.
Außerdem ist dieser bekannten Einrichtung keine Anregung zu entnehmen, wie mit modernen Druckaufnehmern, die ein druckproportionales elektrisches Signal bereitstellen, eine Niveau- oder Füllstandsmessung eines flüssigem Mediums realisiert werden könnte.Besides that is to take this suggestion no suggestion, as with modern pressure transducers, which are a pressure proportional electric Signal provide a level or level measurement of a liquid medium could be realized.
