well they have water pressure gauges for this sort of thing.. it would be right on the outlet.. i would change flow by pinching down on the pump inlet a few inches back... between the res and the pump. if it cavitates i would squeeze it before the res and that wouldnt be a problem.

well mesuring presssure drop across a known restriction is... well its alot more complicated than my method and would not be cost effective from what it seems. correct me if im wrong but i think im right on this.

but anyway.. the measurment point would be right at the pump outlet as i said as this would be where the measurment would be accurate... anywhere else and it would incur the presure drop from the tubing lenght, blocks and whatnot and screw up the calculations.

thanks for the input incorherent.

but stil the question remains will it work?
