No cost wind damping procedure
Overall, what works best is to have one tube run to the outdoors, with a T-connector in the outdoor end
connected to two equal length tubes that are placed as far away from the building as possible.
Place the outdoor pickup tube at least ten feet away from the building's wall and at ground level. This will
eliminate the stagnation pressure developed when the wind hits the wall.
If pressure is still too high place a T on the end of the tube and tape it to the middle of a plastic dinner plate
or smaller plate. Tape the T to the concave surface of the plate, which is the one that would normally be
facing up.
Invert the plate on the ground so the plate covers the tube. This will prevent the velocity from impinging
on the end of the tube.
If further wind damping is required, connect a T-connector to the end of the outdoor tube and connect two
other 15-foot tubes, and then repeat the step of covering the tube ends with the plate.
This should work well and cost nothing. Let us know what the result is.
