Product Description

Based on the advantages of similar products at home and abroad, and combining with the actual situation in China, AL2000 series magnetic level gauge is a new generation of liquid level measuring instrument, which is produced on the basis of the standard of magnetic level gauge HG/T21584-95 promulgated by the former Ministry of Chemical Industry of The People's Republic of China, and can be used to detect the liquid level (interface) of liquid media in equipment made of various materials. Because the detection part of level gauges in this series is completely isolated from the display part, it has unique advantages in measuring the liquid level of high temperature, high pressure, high viscosity, toxic, harmful and strongly corrosive media, and has better reliability and safety than traditional glass tube and base type level gauges.

Coupled with a level control and alarm switch, the series of level gauges realize level control, alarm, and linkage. Coupled with a built-in integrated level transmitter, it can convert the level (interface) signal into a two-wire 4~20mADC standard signal to achieve long-distance liquid level detection and control. It is widely applied to liquid level measurement and control in the various industries' production processes-electric power, petrochemicals, chemicals, metallurgy, environmental protection, shipping, construction, food, and more.

Structural and Principle
The magnetic level gauge is developed according to the buoyancy principle (Archimedes) combined with the magnetic coupling effect. When the liquid level in the measured container rises and falls, the float in the main pipe of the level gauge also rises and falls, and the permanent magnetic steel in the float is transmitted to the fi eld indicator (ruler) through the magnetic coupling effect to turn the red and white turning columns. When the liquid level rises, the turning column is turned from white to red. When the liquid level drops, the turning column turns from red to white. The red-white junction of the indicator is the actual height of the medium level in the container
