The invention relates to a level indicator, especially for a conductive fluid contained in a container (1), comprising two probes immersed in the fluid (6) that are fed by a suitable electronic system. The inventive indicator is further characterized in that one of the probes "B" (4) is configured by a plurality of diodes (D1-Dn) that are interconnected in series along the height of the fluid level to be measured with their ends contacting the liquid. The other probe "A" (5) is configured by a conductor that contacts the fluid (2). An end "C" (7) is connected to diode "D1". A resistor "R1" is connected to the conductor "A" downstream of the diode D1. |
