Trying here to substitute logic for knowledge.
Assume flow meters on concentrate and permeate. If I open the concentrate valve fully then I assume there would be little to no permeate flow. As the concentrate valve is closed permeate flow would begin, so it would seem that the permeate flow is controlled by the concentrate valve.
If the concentrate valve is closed so as to give permeate flow its calculated volume, i.e. 40 gpd (105ml/min.) is there a way to figure the concentrate flow? Axeon gives a 4:1 ratio @ 50 psi but I assume it would be less (or more efficient) @ 100 psi.
I am asking this so that I can make sure that the flow meters I buy have the correct flow range. (I realize this is probably overkill and I would probably do ok with a capillary flow restrictor but complex systems amuse me and satisfy my need to quantify stuff.)
