I hope I can explain myself correctly. I believe you use a wand to go into a port and measure air speed or flow I guess. If the air speed drops alot on a inside radius of port, would you want to fill the radius to get speed up or get a larger radius to help speed up air? If it sounds like I don't know what Im talking about just say so as I have not been around flow benches all but a couple times
