Abstract
An electronic liquid level gauge for measuring the level of a liquid contained in a vessel by employing an electrode pair immersed in the liquid. The electrode pair is associated with an oscillator which generates pulses of a repetition period directly proportional to the electrostatic capacity of the electrode pair. A counter is provided which is reset by an oscillator pulse and starts counting reference pulses of a predetermined repetition rate with a predetermined time delay relative to the occurrence of the oscillator pulse.
