Magnetic Gas Tank Level Indicators

Install the magnetic float ball on a stem or through tube inside the tank. As the liquid level changes, the float moves up or down, and the magnet inside actuates external sensors or reed switches mounted along the tube. This converts mechanical float movement into readable level signals for monitoring or control systems.

A magnetic float indicator continuously tracks fluid level inside the tank. As the level drops, the float descends and the magnet shifts position, triggering level markers or electronic sensors on the outside of the tank. This gives you a real-time, accurate reading of remaining volume without opening the tank or using dip sticks.

Our magnetic float balls are manufactured from 304 and 316 stainless steel, making them resistant to corrosion, high pressure, and a wide range of chemicals. 316 stainless steel is especially suited to corrosive or marine environments. Other materials are available upon request for specialized applications.

Yes. We can tap any thread specification including 1/4-20, 3/8-16, 1/4 NPT, 3/8 NPT, 1/2 NPT, 5/8-11 UNC, and 3/4 NPT, among others. Custom through tubes, hooks, and fittings are also available to ensure seamless integration with your existing measurement or control system.

Yes. All float balls can be pressure-tested to meet your specific system requirements. We have dedicated testing equipment to validate performance under high-pressure conditions, ensuring reliability in demanding industrial environments such as steam traps, vacuum tanks, and chemical processing systems.

Round float balls are available in sizes from 1-1/2" to 14". Oblong floats range from 2x6" up to 9x14" with various thread options. All shapes are available in matte, brushed, or polished finishes. Custom sizes can be added to inventory to meet your exact application requirements.
