Our liquid level indicator, utilizing the communicating vessel principle, buoyancy principle, and magnetic coupling technology, enables real - time accurate liquid level monitoring. As the liquid level changes, the magnetic flip columns on the panel clearly show the level status, with the red - white junction marking the actual liquid height.
Working Principle
The liquid level indicator operates based on multiple key principles to deliver outstanding performance. First off, the communicating vessel principle ensures that the liquid level displayed on the indicator matches that in the measured container. Then, thanks to the buoyancy principle, the float moves up and down as the liquid level changes. Most crucially, through the magnetic coupling effect, the permanent magnet inside the float transmits the liquid level change information to the magnetic flip - column indicator panel.
When the liquid level rises, the flip columns turn from white to red; when the liquid level drops, they switch from red to white. The distinct boundary between the red and white columns on the panel directly represents the actual height of the liquid level in the container, providing an intuitive and precise way to monitor the liquid level. This design not only guarantees accurate level indication but also offers a durable solution — magnetic coupling eliminates mechanical wear, making the indicator reliable for long - term use. It's a must - have for industries requiring constant liquid level tracking!
