Product Description
The UHC type magnetic flap liquid level gauge is made up of measuring body,dual-colored display cylinder, ruler, top&low flange, magnetic ball and transmitter (4-20mA). Based on buoyance principle, the magnetic ball in the body of the level gauge is up or down with the liquid level changing and makes dual-colored turning to show the level of medium. Each cylinder is with two-color axisymmetric structures. The distance of two cylinders is 10mm. Red side of display cylinder indicates liquid and white side display cylinder indicates air. Besides measuring liquid level, it also could measure the interface of the two kinds of liquid.

Workshop and Processing
When the liquid level in the measured container rises or falls, the magnetic float in the body tube of the level gauge will rise or fall accordingly. The permanent magnet steel in the float is transferred to the magnetic flap indicator through the magnetic coupling to drive the red and white When the liquid level rises, the tilting column turns from white to red. When the liquid level drops, the tipping column changes from red to white. The red and white junction of the indicator is the actual height of the liquid level in the container to achieve a clear indication of the liquid level. The axial distance between two adjacent indicator plates is 10mm, and the liquid level indication error is &; plusmn company; 10mm.
According to the principle of buoyancy, the float moves up and down in the measuring tube as the liquid level rises and falls. The permanent magnet in the float drives the red and white column to rotate 180 degrees through magnetic coupling. When the liquid level rises, the column changes from white to red, and when it falls, the column changes from red to white to realize the liquid level indication.
