ABSTRACT:
A device for determining the level of a liquid in a tank comprising a manually-operated spring-loaded piston in a piston chamber, wherein the chamber is connected to the tank and a gauge. Pressing the piston causes the gauge to reach the pressure at the bottom of the tank, which is calibrated to give the height or level of the liquid in the tank.
