Product Overview
The ADDA-LE-68 Series magnetic level gauge is used for detecting liquid level or interface in equipment made from various materials. The product details state that the detection section and display section are completely isolated, making it suitable for high-temperature, high-pressure, toxic, harmful, and strongly corrosive media.
With a built-in integrated level transmitter, the level or interface signal can be converted into a two-wire 4~20mADC standard signal for remote level detection and control.
Applications
Product details include electric power, petrochemical, chemical metallurgy, environmental protection, and other industries.
Working Principle
The magnetic level gauge is developed according to the buoyancy principle, also known as Archimedes’ principle, combined with magnetic coupling. When the level in the measured vessel rises or falls, the float inside the main tube of the level gauge rises or falls accordingly.
The permanent magnet inside the float transfers the magnetic coupling action to the on-site indicator, driving the red and white flaps to turn. When the level rises, the flaps change from white to red; when the level falls, they change from red to white. The red-white boundary indicates the actual medium level in the vessel.
