Abstract
In an environment having two or more immiscible liquids wherein a first liquid floats on top of the second liquid, a gauging system which senses the depth of the first liquid which is floating on top of the second liquid. A float holding a capacitance probe which passes through the entire depth of the first liquid maintains the probe at the free surface level at all times. A cable wrapped around a drum and connected to the float is used for determining the free surface liquid level.
