Abstract

Es wird eine Füllstandsanzeige, insbesondere eines in einem Behälter (1) enthaltenden, leitfähigen Fluids beschrieben, umfassend zwei im Fluid (6) eingetauchten Sonden, die durch eine geeignete Elektronik gespeist werden. Gemäss der Erfindung ist eine der Sonden 'B' (4), durch eine Vielzahl von Dioden (D1-Dn), die untereinander längs der Höhe des zu messenden Fluidfüllstandes mit den Enden im Kontakt mit der Flüssigkeit in Serie geschalten. Die andere Sonde 'A' (5) ist durch einen Leiter in Kontakt mit dem Fluid (2) gebildet. Ein Ende 'C' (7) ist nach der Diode 'D1' geschaltet. Ein Widerstand 'R1' ist nach der Diode D1 mit dem Leiter 'A' verbunden.
