I didn't give this much thought before I purchased a vacuum/pressure gauge. It's one of those single port devices that measures negative or positive pressure from 0 to 10 psi or 0 to 30 in/Hg. Exact model is here.
My plan was to place tubes at various locations under the cowl to read the pressure at that specific spot. I could run several lines, label them, then swap the gauge to a different hose in the cockpit while flying. But, I'm not sure if this instrument is going to work. Maybe it will....it just seems to need a pretty good amount of suction to move the dial, and I'm not convinced I'll be able to read that much variation under the cowl.
What do you guys think? I really don't want to build a manometer for inside the cockpit, so the dial idea was ideal. Any help is greatly appreciated.
