Frequently Asked Questions

What is a magnetic level gauge and how does it work?

A magnetic level gauge uses a float ball with an integrated magnet that rises and falls with the liquid level inside a chamber or tank. The magnet's movement actuates external indicators or switches, providing a visual or electronic reading of the liquid level without direct contact with the fluid, making it ideal for sealed or pressurized systems.
