Working Principle
The controller working principle is based on the Archimedes'principle, i.e. the floating ball immersed in the liquid, forced an upward buoyancy which is equal to the liquid weight drained off by the floating ball with the variation of the liquid level in the vessel，the floating hall will go up and down and drive the connetion rod and the iron core to move upwards and downwards, and make the relative position to be changed between the iron core and the magnetic steel the magnetic force acts the micro-switch to send the on-of signal，carry out the controlling and alarming function for the liquid level。
