Abstract: A liquid level indicator for storage tanks including a cover member for covering an opening at the top of the storage tank, a central rod extending downwardly from the cover member into the storage tank, and a float movably disposed on the central rod. A vertically movable first rod assembly is connected to an upper portion of the central rod, and a vertically movable second rod assembly is connected to a lower portion of the central rod, with the float being disposed therebetween so that the float contacts and moves the first rod assembly when the storage tank is substantially filled, and the float contacts and moves the second rod assembly when the storage tank is near empty. Switches are associated with each of the first and second rod assemblies to activate signal members when either of the first and second rod assemblies are vertically moved to indicate when the storage tank is substantially filled or when the storage tank is near empty.
