A liquid level control system by using a float sensor works on the principle of buoyancy which states a float immersed in a liquid is buoyed towards upward direction by an applied equal force to the weight of the displaced liquid as a result the body drives partially and gets submerged upon the liquid surface and covers the same distance the liquid level moves.
Level sensors detect the level of liquids and other fluids and fluidized solids including slurries granular materials and powders that exhibit an upper free surface substances that flow become essentially horizontal in their containers or other physical boundaries because of gravity whereas most bulk solids pile at an angle of repose to a peak.
