What component in a Tank Level Indicator (TLI) measures liquid levels as they change?

The magnetic float is the component in a Tank Level Indicator (TLI) that measures liquid levels as they change. This device typically consists of a float that is buoyant and moves upward or downward with the liquid level. As the liquid level fluctuates, the magnetic float ascends or descends along a guide tube. This movement is then translated into a measurable signal by a magnetic sensor or a series of switches, providing real-time data about the current level of liquid in the tank.

The functionality of the magnetic float allows for continuous level monitoring and is highly reliable in various conditions, making it a preferred choice in many applications. This method effectively captures changes in liquid levels without requiring direct contact with the liquid, which is beneficial in scenarios involving corrosive or hazardous materials.
