Abstract
A tank level detection apparatus for indirect measurement of a liquid level in a tank is disclosed. The apparatus includes a second liquid at least partially stored in a reservoir and a one-way valve, which communicates between the reservoir and the tank. A sensor is used to determine a physical characteristic of second liquid from which the level of the liquid in the tank can be determined.
