[Chemical Knowledge]：Principle and Application of Magnetic Level Gauge

Read： 821 Time：14months ago Source：Transform the World with Simplicity

Magnetic flap level gauge is an instrument that uses the principle of magnetic induction to measure liquid level. Its structure is mainly composed of a magnetic flap, liquid level gauge, magnetic steel and so on. The principle of the magnetic flap level gauge is to convert the sensitivity of the magnetic force to the liquid level into a mechanical displacement signal, so as to realize the monitoring of the liquid level.

When the liquid level is at a low level, one end of the magnetic flap is close to the magnetic steel, and the other end is away from the magnetic steel. When the liquid level rises to a certain extent, the magnetic flap will turn over, making the magnetic steel close to the other end, thus changing the magnetic induction. These changes are converted into electrical signals, and are read and displayed by the level gauge ruler, so as to achieve the purpose of liquid level measurement. The advantages of

magnetic flap level gauge are simple structure, convenient use, and suitable for liquid level detection of various liquids. It can measure the liquid level of chemicals, solvents, petroleum, water and other liquid media, so it is widely used in chemistry, papermaking, printing and dyeing, electric power, environmental protection and other fields.

In the chemical production process, accurate measurement of liquid level is one of the basic conditions to ensure production quality and safety. The magnetic flap level gauge can not only complete the monitoring of the on-site liquid level, but also can be used in conjunction with the automatic control system to realize unmanned liquid level monitoring and control. Therefore, it is widely used in chemical, pharmaceutical, food and other industries. As a simple, efficient and reliable liquid level detection technology,

magnetic flap level gauge has irreplaceable advantages. In various industrial fields, the magnetic flap level gauge has become a key liquid level detection instrument, which plays an important role in ensuring production safety and improving production efficiency.
