Abstract:
An apparatus for sensing a level of fluid within a container in combination with the container, the apparatus comprising:a support coupled to the container having an axis; a first float having first and second ends, the first float pivotably coupled about the axis of the support proximate the first end, the first float being buoyant so that the first float pivots about the axis defining an angular position of the first float; a second float having first and second ends, the second float displaced from the first float and pivotably coupled about the axis of the support proximate the first end, the second float being buoyant so that the second float pivots about the axis defining an angular position of the second float; and a position sensing mechanism for sensing the angular positions of the first and second floats and responsively determining the level of fluid within the container.
