Attitude compensating indicator

An indicator for measuring the liquid content of a container comprising:

• an attitude compensating sensor comprising at least two variable resistor assemblies individually mounted at opposite ends of said container and disposed for electrical series connection with each other,
• each resistor assembly comprising a housing mounted within said container and attached to one wall thereof, said housing comprising a fluid-tight chamber supported and located near the bottom of said container, said chamber having at least one stationary wall and at least one movable wall, said movable wall capable of movement with respect to said stationary wall in response to changes in liquid weight, a weight-responsive variable resistor mounted within said chamber in contact with said stationary wall and said movable wall, and a conduit providing fluid registry between said chamber and the ambient atmosphere outside said container, said conduit mechanically supporting said chamber within said container, said conduit attached at one end thereof to said stationary wall, and extending into attachment at the other end thereof to a wall of said container,
• an electrical connection means extending into contact between said resistor assemblies,
• wherein the movement of said movable wall causes a change in the electric current output of said resistor and the total resistance of said sensor received from each of said variable resistor assemblies remains constant for a particular level of liquid content.
