Yesterday afternoon, a customer from Fujian called to inquire about a magnetic flap level gauge purchased from a manufacturer in Weifang, Shandong Province. The worker had installed the magnetic flap level gauge before using it, and the flipping column had already turned flower. They are now calling us to inquire about how to handle the return flower of the magnetic flap level gauge? After listening to the questions raised by the customer, we explained them carefully. Later, the customer followed our instructions and made all the necessary adjustments. The customer was very satisfied with our Jiangsu Runyi manufacturer and expressed that there is still a second phase project ahead. If they need to purchase instruments, they will contact us directly. Today I will talk to you about how to deal with the demagnetization of the magnetic flap level gauge?

When we return the newly purchased magnetic flap level gauge from the manufacturer, we need to do the following:

Firstly, how to deal with the demagnetization of the magnetic flap level gauge? Firstly, check the issue with the magnetic flip level gauge itself. The profile of the flip bead has burrs during processing, which can affect the smoothness of the flip column during flipping and lead to the appearance of flower face phenomenon.

Secondly, how to deal with the demagnetization of the magnetic flap level gauge? After installing the magnetic flap level gauge, the production workers of the level gauge ship it to the customer through logistics. During transportation, the level gauge sways back and forth, the float moves back and forth, and the outer beads turn over. Users can use a small magnet to brush the panel up and down before use to make their colors consistent. At this point, it can be put into use.

Thirdly, how to deal with the demagnetization of the magnetic flap level gauge? When encountering harsh on-site conditions, the dust level gauge is often in an environment with water droplets, causing the beads to deform or get stuck when inverted. At this time, the floats in other floats are working normally, but some parts of the panel cannot be seen clearly, resulting in messy patterns.

Fourth, how to deal with the demagnetization of the magnetic flap level gauge? The liquid flow rate is too high, resulting in too fast inertia of the flipping column. After installing the liquid level gauge, during the process of using the liquid, the liquid flow rate is too high, causing the flipping column inertia to be too fast. The flipping column will instantly flip 360 degrees, which will also cause the flipping column to flip over.

Fifth, how to deal with the demagnetization of the magnetic flap level gauge? The on-site temperature is higher than the production temperature of the liquid level gauge. When the user selects the liquid level gauge, the working temperature is not provided accurately. If the on-site temperature is higher than the production temperature of the liquid level gauge, it will cause severe deformation of the panel (injection molded part) in long-term use, and different degrees of deformation will lead to the occurrence of column flipping and flower face phenomenon.

How to deal with the demagnetization of the magnetic flap level gauge?Here are a few methods

Firstly, the anti demagnetization flipping process is adopted for the flipping column of the magnetic flip plate level gauge, which is mainly achieved through optimizing the magnetic coupling design and material selection

Secondly, magnetic coupling structure design

Adopting non-contact magnetic coupling transmission technology between magnetic float and flip column to avoid wear and demagnetization problems caused by traditional mechanical contact. The magnetic steel inside the float is driven by a magnetic field to flip the column, reducing direct contact friction and extending its service life.

Thirdly, material selection

The flipping column is made of high-strength stainless steel or polytetrafluoroethylene material, and the surface treatment adopts anti-corrosion technology (such as stretching and flanging technology) to ensure stable performance in corrosive media or high temperature environments, avoiding demagnetization problems caused by material aging. ‌

Fourth, magnetic isolation measures

Add magnetic isolation materials (such as aluminum or copper shielding layers) around the magnetic switch to reduce external magnetic field interference and prevent misoperation caused by magnetization. Regularly check whether the magnetic switch has magnetization phenomenon and maintain and adjust it in a timely manner. ‌

Fifth, process optimization

Remove burrs and sharp edges during the processing to avoid column jamming or demagnetization caused by processing defects. Adopting a blind spot free measurement structure to ensure accurate liquid level indication.
