Mechanical Float Level Gauges for Water Tanks

Round float balls are available in diameters from 1-1/2" up to 14", including 2", 3", 3-1/2", 4", 5", 6", 7", 8", and 10". Oblong floats range from 2x6" up to 9x14". Custom sizes beyond standard inventory can be manufactured to meet your exact tank geometry and buoyancy requirements.

Yes. Any thread specification can be tapped into the float ball. Common thread options include 1/4-20, 3/8-16, 1/4 NPT, 3/8 NPT, 1/2 NPT, 5/8-11 UNC, and 3/4 NPT. Custom fittings, through tubes compatible with 3/8" to 3/4" rods, and magnet integration are all available based on your system's connection requirements.

Yes. The 304 and 316 stainless steel construction makes these float balls highly suitable for food processing environments including tanks and vats holding oils, syrups, and water-based liquids. The polished and brushed finish options further support sanitary requirements. Custom configurations ensure compatibility with industry-specific fittings and hygiene standards.

Magnet integration involves custom-sourced magnets assembled inside the float ball shell. This is used in systems where a magnetic trigger is required to actuate a reed switch, sensor, or valve without direct fluid contact — common in sealed tanks, high-purity water systems, and automated level control applications where electrical or reed-based sensors are deployed.

Yes. Pressure testing equipment is available in-house and testing can be performed to meet custom specifications. This ensures each float ball maintains structural integrity and watertight sealing under the operating pressures of your specific system — critical for high-pressure industrial tanks, vacuum tanks, and sump pump applications.

Three finishes are offered: Matte (unfinished with visible weld ring), Brushed (smoothed weld seam), and Fully Polished (mirror finish). While all finishes perform reliably in water tank environments, the polished finish reduces surface roughness that can harbor deposits, making it preferred for potable water, food-grade, or pharmaceutical tank applications requiring easy cleaning and contamination control.
