Liquid Level Gauge - Magnetic Flapper in English

A magnetic flapper liquid level gauge is an instrument used to measure and indicate the level of liquids in tanks or vessels. It consists of a float with a magnet inside that moves up and down with the level of the fluid. *ternal to the tank, there is a transparent column with scale markings, along which a magnetic indicator or "flapper" moves to show the level.

This type of gauge is widely used in various industries, including chemical processing, oil and gas, water treatment, and more. It provides a simple and reliable way to monitor the level of liquids without the need for electrical power or complex mechanisms.

The working principle of a magnetic flapper liquid level gauge is based on the law of buoyancy and the interaction between magnets. When the liquid level rises, the float inside the tank also rises, causing the magnet to move upward. This movement is then transmitted through the tank wall to the external indicator, which is attracted or repelled by the magnet, displaying the corresponding level.

One advantage of using a magnetic flapper liquid level gauge is its high visibility. The transparent column allows operators to easily observe the level from a distance, even under varying lighting conditions. Additionally, the magnet and indicator are designed to provide clear and accurate readings, ensuring reliable monitoring of liquid levels.

In terms of installation, the gauge can be mounted at the top or side of the tank. It requires a small opening for the transparent column to pass through, which is typically sealed to prevent leaks. The materials used for construction vary depending on the application requirements, with options such as stainless steel, PVC, or other corrosion-resistant materials available.

Another key feature of magnetic flapper liquid level gauges is their compatibility with a wide range of liquids. They can handle both clean and dirty fluids, as well as liquids with high viscosities or those containing solids. This versatility makes them suitable for various industrial processes where different types of liquids need to be monitored.

It is important to note that magnetic flapper liquid level gauges are not suitable for highly volatile or hazardous substances, as the transparent column may pose a risk in certain environments. In such cases, alternative measuring devices should be considered.

In conclusion, the magnetic flapper liquid level gauge is a reliable and cost-effective solution for monitoring liquid levels in tanks and vessels. It offers clear visibility, accurate readings, and compatibility with a wide range of liquids. With its simple yet effective design, it is an essential instrument in many industries.
