 What is the magnetic flap level gauge

A magnetic flap level gauge is a type of level measurement device used primarily in industrial applications to determine the level of liquids inside tanks or vessels. It consists of a magnetic float enclosed within a chamber connected to the tank.

Here’s how it typically works:

  1. Float with Magnets: The gauge includes a float with built-in magnets. This float moves up and down inside the chamber as the liquid level changes in the tank.

  2. Indicator: Inside the chamber, there is an indicator or flap that flips according to the position of the float. This indicator usually has contrasting colors on each side (e.g., red and white) and is easily visible through a transparent sight glass.

  3. Magnetic Coupling: The magnets in the float interact with magnets on the indicator. As the float moves with the liquid level, it causes the indicator to rotate or flip, showing the current level of the liquid.

  4. Reading the Level: Operators can read the liquid level by observing the position of the indicator flap. The position of the indicator corresponds to the level of the liquid inside the tank.

Advantages of magnetic flap level gauges include their simplicity, reliability, and suitability for a wide range of liquids and operating conditions. They do not require external power and are easy to install and maintain. They are commonly used in industries such as oil and gas, chemical processing, water treatment, and food and beverage production where accurate level measurement is crucial for operational safety and efficiency.
