Frequently Asked Questions

What is a float level gauge?

A float level gauge is a device used to measure or monitor the level of liquid inside a tank or vessel. It uses a buoyant float that rises and falls with the liquid surface. As the float moves, it transmits the level reading to a connected indicator, valve, or sensor, providing continuous and reliable tank content measurement.
