Fuel Tank Top Mounted Stainless Steel High Alarm Level Switch

Think of a float switch as your tank’s silent sentry. 

A buoyant capsule—molded from chemical-resistant polypropylene or mirror-finish 316 L stainless steel—glides effortlessly up and down the liquid column. 

Nestled inside is a tiny, magnet-driven reed switch potted in epoxy, completely sealed from moisture, fumes and vibration. 

The moment the liquid level nudges the float to the pre-selected height, the magnetic field flips the internal contacts closed, instantly completing the circuit. 

No power supply to wire, no span or zero to tweak—just a crisp, reliable ON signal every time the level says “go.”
