How does magnetic level control work?

Learn about the principle and applications of magnetic level control in industrial processes.

Magnetic level control is a robust and reliable solution for measuring liquids in industrial tanks and reservoirs. It combines the simplicity of a magnetic float with the precision of an electronic transmitter, such as guided wave radar. Thanks to this integration, the system offers redundant measurements, increasing operational safety in critical processes.

In operation, the system utilizes an external chamber connected to the tank. Inside this chamber, a magnetic float tracks the liquid level variation. As the liquid rises or falls, the float moves and activates visual indicators attached to the outside of the tube. As a result, the operator can easily view the level, even from a distance. Furthermore, the system does not rely on electrical power to provide visual indication, making it extremely useful in power outage situations.

To enhance automation, it's possible to integrate a guided wave radar transmitter. This technology sends continuous, real-time measurements to systems such as PLCs or SCADA platforms. This makes remote process control more efficient and safer.

Another significant advantage is its durability. Magnetic level control withstands harsh environments and can operate under severe temperature, pressure, and corrosive conditions. Therefore, it is widely used in the chemical, petrochemical, pharmaceutical, and food industries.
