Quick Tips Video | How to Weight a Float Ball

In this video, Jerry from Kimray and Tim from Superior Fabrication (SFI) discuss utilizing a float ball with a float arm inside a vessel along with a mechanical dump valve. In a production process the oil floating on top of the water has an interface line.

For this float to be able to sense the water level to create the discharge action, we must to weight it. This allows the float to pass through the upper oil pad and sense the density of the water. In the video, we use a 7×12 float that does not have any additional connections. Since we only have one connection we have to drill a hole where the coupling is.

We recommended threading a short nipple in to protect the threads. We drill through then end of the float ball with a half-inch drill bit. Once the hole is drilled, we pour in dry sand, though you could also use BBs. We recommend dry sand because if you overfill, wet sand is very difficult to get outWe test our float ball in fresh water.

If it will float on fresh water it will definitely work in brine water. We submerge the ball in the bucket of water and it still has quite a bit of surface area protruding from the water, so we don’t have enough sand inside. After adding more sand it achieves the level we need and is ready to go inside a vessel.

One last note: Be sure to tape or dope the threads carefully because it must be sealed and not let any fluid inside during production.
