What’s available for that? I know Neptune has flow monitors but you need a minimum flow rate for it to work and I don’t think there would be enough with an rodi system. Plus he’s trying to phase out his apex stuff.
And has a not insignificant amount of fines/dust, which you need to flush prior to use.
I use this
Looks good. One amazon reviewer said he had to install it on the input side of his rodi because the output flow was too low to register. The manufacturer shows the flow should be between .3-3.5 GPM. It would work good then for the carbon block but not DI.
That should be fine, those carbon blocks are the big unknown of the situation. RO membrane, you can have a TDS meter before and after to check it's usefulness, DI resin, you can do the same or with color changing resin you know when it's good. With carbon blocks you have to tee off before the membrane and use a chlorine test strip, which don't get me wrong isn't a horrible thing to do, but nobody likes testing, once you figure out the useful life of that particular membrane simply look at numbers on a display to see if it's getting time to change.
on the input side anyway to track total gal Through the sediment/carbon/chloramine filters and membrane(s)
Keep track of how many gal have gone through any particular stage of your setup since you last changed it. My chlorplus 10 block is only rated for 1500 gal.
How many gallons do you think your media can handle before needing to be changed?
