I.Summary:
UHZ - 20 series magnetic column level gauge is suitable for the level measurement and control in various industrial automatic process control.Divided into top mounted and side mounted,is widely used in petroleum, chemical industry, water treatment, pharmaceutical, electric power, papermaking, metallurgy, shipbuilding and boiler.

II.Working principle:
UHZ-20 series magnetic column level gauge, is mainly designed and produced on the basis of the principle of buoyancy and magnetic force . Float with magnets (magnetic float for short) in the position of the measured medium affected by buoyancy effect. Liquid level changes lead to the change of the magnetic float position, magnetic float and magnetic static magnetic coupling effect , lead to the magnetic double column flip, which reflect the container level. Cooperate with remote transmitter, output standard current value (4 ~ 20 ma) signal and switch signal, so as to realize the perfect combination of field observation and remote control
