I just installed a Pentair intelliflo variable speed pump. I have the Pentair Solartouch solar controller connected to it, as well as a flowvis flow meter. I'm trying to set the recommended flow rate for the Fafco Sunsaver panels that I have installed (2 story house). From what I've read, the optimal flow rate is 4 GPM per panel. I have 7 panels. When I adjust the speed of the pump so that it shows 28 GPM on the Flowvis, it doesn't seem as if the pump is pushing enough water, as I start to see air in the flowvis, and get bubbles in the pool. To get to the point of no air bubbles, I have to set the speed to around 2500 RPM, which is showing 50 GPM on the Flowvis. Am I missing something, or am I stuck with having a higher flow rate due to my setup?
