Magnetic Level Gauge- LLI73

The magnetic level gauge is a suitable tool for measuring and monitoring the liquid level of open and pressurized tanks. Due to the special design of LLI73 series magnetic level meters, they are suitable for use in many services (toxic, harmful, flammable, hot, cold, etc.). The LLI73 easily connects to a tank through its connectors.

The LLI73 gauge consists of a body or column with a float with a permanent magnet inside. The float is placed on the surface of the liquid and goes up and down with it. The magnetic field inside the float is coupled to the magnetic field of the indicator magnet and moves it. The inductor is mounted on the body and has no contact with process fluid.

In order to control the level of liquids in the processes, control devices such as switches and magnetic transmitters can be easily used on LLI73.
