Oil Tank Float Gauges

Typically, the reading is taken from the center or top of the float ball, depending on the gauge design and manufacturer specifications. For most stainless steel float systems, the top of the float aligns with the indicator mechanism, so checking manufacturer documentation for the specific model ensures accurate level readings.

Our float gauges are manufactured from 304 stainless steel, the most common option, or 316 stainless steel for enhanced corrosion resistance in harsher environments. Both materials offer excellent durability, are food-safe, and withstand exposure to oils, chemicals, and moisture in industrial tank applications.

Yes, float balls can be built with custom-sourced magnets assembled internally for precise magnetic level detection, along with custom threads, NPT fittings, hooks, or through tubes. These modifications allow the float to integrate directly with existing sensors, rods, or measurement devices in your oil tank system.

Round float balls range from 1-1/2" up to 14" in diameter, while oblong floats are available in sizes such as 7 x 12", 7 x 16", and 9 x 14", among others. Custom sizes outside standard inventory can also be manufactured to fit specific tank and gauge requirements.

Yes, all float balls can be pressure-tested using dedicated testing equipment to meet custom specifications before shipment. This ensures the float maintains structural integrity and accurate buoyancy performance in high-pressure oil tanks, vacuum systems, and other demanding industrial environments.

Lead times vary based on size, finish, and customization complexity such as magnet integration or thread tapping. Because a large inventory of common sizes is kept in stock, many orders ship quickly, while fully custom configurations may require additional manufacturing time.
