From the O2 tank regulator to the bottom of the flow meter
Top out connects to the stone
From the flow meter top
The O2 regulator is set to 20 psi, this prevents my wort pump from pushing any wort into the flow meter through the stone.
The best flow meter setting, minimal foam is 300 CC/min for my set-up.
