Flowbench build. Fun project that pays dividends

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.

Like the electronics SuperFlow offers?
I assume you meant, 'pitot'?
If so, mine is as well. It was fairly inexpensive, start up wise... I sometimes have issues associated with not enough plenum volume. but I've managed to quell them, for the most part.
I did add a accumulator, in line, on both sensor hoses to help dampen signal. It really calms down the readings and it actually improves repeatability.
In all, I like my oldish machine. Tests are performed very quick.. just long enough to make lift changes. (I still use a lift fixture)
Yes, 100 H2o is a LOT. You're gonna have to use thicker panels ! lol
