Would not a inline psi gauge, of good quality and accuracy, located between the pump and whatever restriction is first in a individual system offer a method of rough flow rates? You'd get a read out of the back pressure caused by all the systems fittings and blocks.

Couldn't you then use that psi reading along with a pumps charted performance to reach a systems flow?

Can someone point out flaws in this reasoning? In a way it seems to easy to me, but don't know why.

Thanks

edit: Gauge in mind is on page 491 of McMaster's, digital grade 1A, only digital on that page, resolution of .01 psi and 1% accuracy. I'd be interested in the lowest scale of 0-30 psi.
