UQK-400 Ball Float Level Controller
Summary
UQK-400 Ball Float Level Controller is suitable for fluid level or interface controlling and alarm for different
kinds of open or pressurized vessels in production process in petroleum, chemical, power, paper-making and food
industries, etc.
Structure principle
UQK-400 Ball Float Level Controller is composed of float
ball, ball connecting rod, iron core unit, magnetic switches
and signal conversion device. The float ball floats up and
down with liquid level changes in the vessel and make ball
rod and iron core unit move up and down. This makes the
position of the magnet steel in the iron core changed.
Through the magnetic coupling, the magnetic switch or the
signal conversion device act and micro-active switch,
mercury switch or reed switch act, too. So, in this way, the indicator realizes the functions of liquid level
controlling and alarming.
