In looking at flow meters the requirements for an accurate reading for the Blue-White meters are that you have straight pipe for 10X the diameter of the pipe before the meter and 4X after it. For 2" pipe that's 28" of straight pipe which I don't have anywhere on my pad. Which got me to thinking - what if I measured at each of my returns and summed the results?
I am imagining a setup with a hose that attaches to the return port and gently curves to a straight section of same sized pipe of proper length with the flowmeter on it and then a hose back into the pool.
I'm assuming that the rig and the rise in elevation to deck height (about 15-18") would not create a significant enough back pressure to affect the individual return port's flow which I may be wrong about...
I'd love some feedback from the experts on here
