Fuel Measuring Instrument Electronic Magnetic 4-20mA Water Oil Measurement Tank Level Gauge
The UHC type magnetic flap liquid level gauge is made up of measuring body,dual-colored displaycylinder, ruler, top&low flange,magnetic ball and transmitter (4-20mA).Based on buoyanceprinciple,the magnetic ball in the body of the level gauge is up or down with the liquid levelchanging and makes dual-colored turning to show the level of medium. Each cylinder is withtwo-color axisymmetric structures.The distance of two cylinders is 10mm. Red side of displaycylinder indicates liquid and white side display cylinder indicates air. Besides measuring liquidlevel,it also could measure the interface of the two kinds of liquid.
Features
1. 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.

Workshop and Processing
Principle of the remote magnetic flap level gauge
Because the remote magnetic flap level gauge is composed of a magnetic flap level gauge and a reed remote transmitter, combining the two components of the magnetic flap level gauge &1 introduces the working principle of the magnetic flap level gauge. The basic type of magnetic flap level gauge is a magnetic flap level gauge, also known as a magnetic float level gauge. Based on the structure of the connector, the principle of buoyancy and the magnetic coupling characteristics, real-time measurement of the liquid level is realized. When the liquid level in the measured container rises or falls, the magnetic float used to sense the change of the liquid level in the main measuring tube will also rise or fall. The permanent magnet steel in the float drives the magnetic flap outside the main measuring tube to flip 180&; 180 flux magnetic coupling; the two sides of the valve are painted with different colors (usually red and white) to indicate the position of the liquid level. When the liquid level in the container rises, the valve changes from white to red. When the liquid level in the container drops, the valve changes from red to white. The red and white junction of the indicator is the actual height of the liquid level in the container, so as to realize the accurate measurement and local display of the liquid level.
