Follower type magnetic level indicators provide a clear, continuous, and accurate visual indication of liquid levels inside storage tanks and process vessels. The system works on the principle of magnetic coupling, where a float containing a permanent magnet rises and falls with the liquid level. A follower capsule, magnetically coupled to the float, moves inside a glass tube to replicate the level externally. This design eliminates direct contact between the process liquid and the indicating device, making it highly reliable, safe, and maintenance-free. These indicators are ideal for applications where continuous monitoring is required under varying process conditions.
