ABSTRACT:
An apparatus for indicating the level of fuel in a fuel oil storage tank including a vertically positioned tube having a multiplicity of longitudinally spaced and movable floats therein and a multiplicity of associated reed switches and resistors positioned on the outside of the tube and spaced from each other. The switches are actuated by magnets on the associated floats, which rise and fall with the fuel level, and shunt varying amounts of current by the resistors so that a fuel level readout can be obtained on a meter.
