Float Level Controllers & Monitoring Systems

The float switch is the sensing component of a water level controller. It consists of a buoyant float connected to a switch mechanism. When liquid reaches a set level, the float rises or falls to open or close an electrical circuit, triggering connected equipment such as pumps or shutoff valves to respond accordingly.

To set a float switch level, position the float on its arm or rod at the desired liquid height within the tank. Adjust the float's mounting point or arm angle so the switch activates precisely at the target level. Always test by manually raising and lowering the float to confirm reliable activation and deactivation before commissioning.

Our float balls are manufactured from 304 and 316 stainless steel, making them resistant to corrosion, pressure, and a wide range of chemicals. 316 stainless steel is recommended for more aggressive environments, such as chemical manufacturing or wastewater treatment, where higher corrosion resistance is essential.

Yes, we offer custom magnet integration directly inside stainless steel float balls. Magnets are sourced and assembled to precise specifications, enabling reliable magnetic level detection in complex systems. This is ideal for applications such as sump pumps, vacuum tanks, and industrial liquid level monitoring systems requiring non-contact switching.

We offer round float balls from 1-1/2" to 14" diameter and oblong floats in multiple sizes, including 2x6", 3x5", 7x12", 7x16", and 9x14". Custom sizes are also available. Both shapes can be supplied with various thread specifications, through tubes, and finishes including matte, brushed, and fully polished.

Yes, our stainless steel float balls are widely used in food processing for monitoring oils, syrups, and liquids in large tanks and vats, as well as in wastewater treatment facilities for accurate level monitoring. Stainless steel construction ensures hygiene compliance and resistance to corrosive or high-temperature environments in both industries.
