UQK-400 float level controller consists of float, connecting rod, iron core unit and magnetic switches / signal conversion device. The float movess up and down with level changes in the vessel and makes connecting rod and iron core unit move up and down. This makes the position of the magnetic steel in the iron core change, through the magnetic coupling effect to make microswitch or reed switch acting. It will realize the functions of level controlling and alarming.
