Capacitance-type contents gauges measure which physical property?

Explanation:
Capacitance-type contents gauges measure changes in capacitance caused by the liquid level between two conductors. In these gauges, two plates form a capacitor and the liquid between them (or surrounding dielectric) alters the capacitance as the level rises or falls. The measurement electronics interpret that change in capacitance and convert it into a level indication. This is different from measuring resistance, a visual float position, or pressure, which rely on other physical principles.
