How does a capacitive level meter work?

Capacitance level gauge is a liquid level measurement device based on the capacitance principle. Its working principle is to use the change of liquid level to cause the change of dielectric constant of the medium to change the capacitance value, and realize the measurement of liquid level by measuring the capacitance value. Capacitance level gauge is mainly composed of measuring electrode, reference electrode, capacitance detection circuit and signal processing circuit. When the liquid level changes, the capacitance value between the measuring electrode and the reference electrode will also change, and the height of the liquid level can be calculated.
