Magnetic flap level gauge is a device specially developed for level measurement based on the principles of magnetism and Archimedes' law of buoyancy, combined with the characteristics of mechanical transmission; The magnetic flap level gauge is a basic product, and all other products are extensions based on it; We endow them with more practical functions while detecting liquid levels.

The magnetic flap level gauge has a cavity that accommodates a floating ball, which we call the main tube or shell. The magnetic flap level gauge is connected to the container through a flange or other interface to form a connector; In this way, the liquid level inside the cavity is at the same height as the liquid level inside the container, so the floating ball inside the cavity will rise and fall with the rise and fall of the liquid level inside the container; At this point, we cannot see the liquid level, so we installed a flip column display outside the chamber. When manufacturing the float, we installed magnetic steel at the junction of the float sinking into the liquid and the floating part. When the float rises and falls with the liquid level, its magnetism is transmitted through the shell to the flip column display, pushing the magnetic flip column to flip 180 degrees; Due to the fact that the magnetic flip column is a cylindrical body composed of two semi cylinders, red and white, flipping it 180 ° towards the outside of the flip column display will change color, and the height of the liquid surface is at the junction of the two colors.
　　
The magnetic flap level gauge has a vertical tube with a magnetic float inside. There are many small magnetic objects arranged on both sides of the tube. When the water level changes, the float moves up and down. Due to the magnetic pole effect, the magnetic object flips, and different colors are brushed on both sides of the magnetic object to display the water level. The magnetic flap level gauge is more reliable to use and has a more intuitive display. But when using green and red magnetic materials, such as ordinary incandescent lamps for factory lighting and low light, the observation is not clear enough. In addition, some manufacturers' products may get stuck after a period of use. Therefore, it is important to pay attention to regular cleaning. Common ones include white red, green red, etc. However, strictly speaking, the magnetic flap water level gauge does not directly display the water level of the boiler drum, so it is not commonly used and can be used in boilers with lower pressure and temperature, such as hot water boilers. It also belongs to on-site display (but can be transmitted remotely).
　　
Characteristics of magnetic flap level gauge

1. Suitable for measuring the liquid level and interface of liquid media in containers. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
　　
2. The indication is novel, the reading is intuitive, eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
　　
3. The measurement range is large and not limited by the height of the storage tank.
　　
4. The indicator mechanism is isolated from the tested medium, with good sealing, high reliability, and safe use.
　　
5. The magnetic flap level gauge has a simple structure, easy installation, convenient maintenance, corrosion resistance, no need for power supply, and is explosion-proof.
