Product Details

The UHC type magnetic level indicators 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.

Product Feature

1. Magnetic liquid level gauge has simple structure, good stability and reliability.

2. Independent of medium’s physical and chemical states such as conductivity, dielectric constants, foam etc.

3. Appliable for all kinds of medium environment such as corrosive, toxic and explosive one.

4. Interface measurement or level measurement of 2 kinds of medium with different density.

5. Two-wire 4~20mADC signal output, 0.8’’ or 0.56” LED digital display.
