I use this on the outlet side of my 75 gpd 5 stage reverse osmosis system. It seems easy enough once you know the controls. My biggest problem is that after emptying my expansion tank, the direct performance of the reverse osmosis system just doesn't seem to register on the meter. I often fill 4 to 6 5 liter jugs out of my system when doing water changes in my large tanks. I have two surge tanks that release 6-8 gallons fairly quickly and then slow to a steady trickle. If you never run out of your reservoirs, this may not be a problem, but in my situation it is. I can't find an alternate counter so I'll just leave it as a link in the output. I could be more accurate if I only ever filled 1-2 cans at a time and let them charge in between.
