We are installing a UV system for our pool, and the manufacturer recommends a max flow rate of around 50gpm. There is not enough room to install a flow meter, but there is a psi gauge at the inlet of the UV unit. Is there a way to estimate the flow rate using the psi gauge, and the inlet pipe diameter?
There is a by-pass installed at the UV system so some of the water is by-passed around the UV and onto the heater, so it's not enough to just get the flow rate of the pump, as that wouldn't accurately give the water flowing into the UV, so all I have to go on is the PSI gauge.
