Make Sure it’s a Magnetrol

Magnetrol mechanical buoyancy switches work harder, last longer and perform better in
the most extreme liquid level applications. 

For accurate interface measurement

Make sure you rely on a Magnetrol buoyancy switch for your liquid interface application. From simple to complex separation processes, our float and displacer switches remain virtually unaffected by top-layer thickness and emulsion, to provide outstanding reliability and accuracy in level detection.

For tank overfill protection

The Magnetrol single-point, top-mount buoyancy displacer switches deliver best-in-class overfill protection. The non-sparking, hollow-shell brass displacer provides dual detection of both liquid levels and floating roof, even if the roof becomes submerged, making these switches an ideal independent high-high alarm sensor.

For extreme temperature and pressure conditions

Extreme conditions can stress the abilities of electronic level instrumentation. Magnetrol mechanical buoyancy switches reliably perform in service temperatures up to +1200° F (+649° C) and service pressures up to 5000 psig (345 bar).

For critical applications

When safety and reliability are critical, buoyancy switch technology delivers a robust, time-tested solution for the control industry, by isolating switching mechanisms and magnetic components from the process environment.

The broadest

A deep offering of mechanical buoyancy instruments – including vertical and horizontal float and displacer switches – means Magnetrol can satisfy the needs of all your level control applications with highly reliable, highly repeatable performance.

The longest

Because of our legendary reliability, Magnetrol customers count on our buoyancy switches to work unfailingly hard – and keep on working – decade after decade after decade.
