The liquid level meter is a type of level instrument, and the types of liquid level meters include tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic, sonar wave, magnetic flap, radar, etc. High-temperature liquid refers to the temperature of the liquid medium is higher than 100°C. In waste oil treatment, the temperature of the oil in some containers is higher than 300°C. Ordinary glass tube liquid level meters cannot be used for high-temperature liquid media. Complex and high-speed high-temperature liquid medium liquid level meters are not only costly, but also prone to failure. Therefore, it is necessary to develop a high-temperature liquid magnetic level display device with simple structure, stable performance, no failure, long life, low cost, and easy use.

[0005] The high-temperature liquid magnetic level display device has a thin soft wire connected to the iron ring, the length of the thin soft wire is equal to the height of the stainless steel connecting rod, a liquid level pointer is provided at the lower end of the thin soft wire, and a wire passing ring is provided on the upper flange of the main pipe. The thin soft wire passes through the wire passing ring. When the height of the iron ring is 0, the liquid level height indicated by the liquid level pointer is 0.
[0006] In the high-temperature liquid magnetic level display device described above, the inner diameter of the stainless steel main pipe is 100 mm, the inner diameter of the stainless steel conduit is 20 mm, the outer diameter of the stainless steel conduit is 22 mm, the outer diameter of the stainless steel connecting rod is 16 mm, and the height of the stainless steel main pipe is determined according to the height of the liquid level change in the liquid tank.
[0007] The installation method of the high-temperature liquid magnetic level display device of the present invention is as follows: when installing, there is no liquid in the liquid tank, a permanent magnet is fixed to the upper end of the connecting rod, a stainless steel float is fixed to the lower end of the connecting rod, a mark of the liquid level height is provided on the stainless steel main pipe, and a mark of the iron ring height is also provided on the stainless steel conduit. The stainless steel main pipe is connected to the liquid tank through the lower pipe flange and the upper pipe flange, the lower flange of the main pipe or the upper flange of the main pipe is opened, the stainless steel float and the connecting rod are installed in the stainless steel main pipe, the upper ends of the permanent magnet and the connecting rod are located in the stainless steel conduit, and the iron ring is covered on the outer sleeve of the stainless steel conduit.

[0008] The working principle of the high-temperature liquid magnetic level display device of the present invention is as follows: when the liquid tank is filled with high-temperature liquid, the liquid level in the liquid tank is at the same height as the liquid level in the stainless steel main pipe. When the height of the liquid level changes, the height of the stainless steel float also changes accordingly, the height of the permanent magnet on the top of the connecting rod also changes accordingly, and the iron ring is attracted by the permanent magnet, and the height of the iron ring also changes accordingly. By observing the height value of the iron ring, the height value of the liquid level on the stainless steel main pipe is calculated. When a thin soft wire and a liquid level pointer are provided, the height value set by the liquid level pointer is the height value of the liquid level in the liquid tank. The stainless steel main pipe is opaque, and the height of the liquid level in the liquid tank cannot be directly observed. By using the high-temperature liquid magnetic level display device of the present invention, it is very easy to observe the height of the liquid level in the liquid tank.
[0009] If the high-temperature liquid magnetic level display device of the present invention is used to convert the height signal of the permanent magnet into an electrical signal, it will be beneficial to the electronic display and electronic control of the liquid level.
