Liquid level indicator

An indicator for measuring the liquid content of a container comprising a variable resistor assembly, said resistor comprising:

• A. a housing mounted within said container attached to one wall thereof and extending into proximity with the bottom of said container,
• B. said housing comprising a chamber located near the bottom of said container and an elongated neck extending from said chamber into fluid tight attachment with said container wall for communicating with the ambient atmosphere outside said container,
• C. said chamber comprising an upper wall attached to said elongated neck, and a movable lower wall spaced from and located in substantial alignment with the bottom of said container, said lower wall adapted to move in response to the changes in liquid weight resulting from corresponding changes in said liquid content, and
• D. a weight responsive variable resistor sensor means mounted within said chamber in communication with said movable lower wall, one end of said resistor sensor means connected to said upper wall and the other end of said resistor sensor means connected to said movable wall,
• wherein the movement of said movable lower wall will cause a change in the electric current output of said resistor that will accurately reflect a particular level of liquid content.
