Flowbench build. Fun project that pays dividends

….and didn't you love it when a buddy sticks his hand over the port, to feel the air flow, and half of the fluid got sucks out of the manometer ? :(
My machine uses electronics too. But I still have to enter weather, or it does not repeat well. (Audie)
Love your build though... I'm jealous :)

I almost bought electronics for My manometer bench but I figured being a pilot style bench weather would still be an issue. Bruce has plans now for benches that flow up to 100 depression. That’s some crazy air flow. Lol. He sells some very nice calibration plates that he makes.
