Level troll

A Level troll in and instrument used for measuring the liquid level between two known points. The Level troll works on the buoyancy principal. Leveltrol has a float, which submerses proportionately with liquid level raise in the float chamber. The amount of submersion of the dis placer depends on the liquid density, which produces a torque. The amount of torque produced in measured in terms of % of level.
