Abstract

It consists of a sensor formed by two coaxial metallic tubular elements which define a capacitor whose dielectric consists of the liquid whose level is to be measured, and an electronic circuit which comprises an oscillator stage which can vary with the capacitance of the capacitor formed by the sensor, a frequency/voltage conversion stage, a voltage amplifier stage, a stage for modifying the capacitance/level curve and a second stage for amplifying the output voltage of the signals for actuating an electromagnetic indicator.
