zur Niveaumessung eines flüssigen
Mediums (1) in einem Behälter
(2), dadurch gekennzeichnet, daß ein
mit einer Flüssigkeit
(3) gefüllter,
flexibler erster dünner
Schlauch (4a) an seinem freien Ende einen Druckaufnehmer (5) und
an seinem festen Ende einen Ausgleichsbehälter (6) aufweist, wobei das
feste Ende des dünnen
Schlauchs (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,
daß über dem
ersten dünnen
Schlauch (4a) ein zweiter flexibler dicker Schlauch (4b) vorgesehen
ist, dessen Innendurchmesser erheblich größer als der Außendurchmesser des
ersten dünnen
Schlauchs (4a) ist, daß das
freie Ende des zweiten, dickeren Schlauchs (4b) geschlossen ist
und den Druckaufnehmer (5) aufnimmt und das feste Ende des zweiten
dickeren Schlauchs (4b) mit der Außenwand des Behälters (2)
derart verbunden ist, daß ein

wherein the expansion tank (6) is designed such that acts on the liquid column of the atmospheric pressure and at the same time a liquid leakage is prevented,
in that a second flexible thicker hose (4b) is provided above the first thin hose (4a), the inside diameter of which is considerably larger than the outside diameter of the first thin hose (4a), that the free end of the second, thicker hose (4b) is closed and the pressure transducer (5) receives and the fixed end of the second thicker tube (4b) is connected to the outer wall of the container (2) such that a pressure equalization between the ...
Description
