Abstract
In this paper a new method for a self-calibrating capacitive sensor for threshold liquid level measurement is presented. The basic theoretical ideas are described and illustrated. The theoretical results are proven by field simulations. For practical experiments, a container was manufactured and special electronic circuits were developed. The values of the capacitors are measured, converted into digital values and transferred to the computer. Experimental results are depicted
