The Nivelco NivoCap is a 2-wire capacitance level sensor that has been specifically designed for continuous level measurement of both conductive and non-conductive liquids. The capacitance sensor requires a probe and a reference probe (which can be the metal wall of the tank or installed separately) operate as the opposing plates of a capacitor. When a tank is filling, air is replaced by a medium with a greater dielectric constant, therefore the capacitance is changing in proportion to the change in level. The sophisticated electronics in the capacitance sensor measures the capacitance difference and converts it to an output signal, giving you continuous level measurement.
