Hey Steve, thanks for all your work on this thread! I love data and your graphs are exactly what I am hoping to develop for my system...Looking at your numbers, your cover performs wonders because my pool needs much more chlorine than yours, especially in the summer when the UV breaks it down.
Your +1FC/hr formula is really convenient! I’ve taken a slightly different tact in that I measured exactly how much output flow I was getting with my stenner so that I know precisely how much liquid I am injecting into the pool (oz/min). That number turned out to be substantially different than stenner’s published figure (mine 1.1 oz/min vs published .89oz/min). I wanted to be able to exactly correlate manual additions to stenner additions. It should help if/when I choose to use a liquid chlorine with a different % of chlorine.
Way back earlier in this thread, when I first got my stenner...I mentioned that it shut down (overheated) when I was testing it in the middle of a hot summer day (I also had an ill-advised cover around it at the time). Since then (with additional experience), I have concluded that (for me) there is really no advantage to extending run times for the stenner, as long as I still have the granularity I need to inject precise amounts of chlorine. Now I just want to get the chlorine in the pool quickly...better for the stenner and much better for the wait times for large injections (like your manual injections) if/when those are necessary.
Once I get my system fully up, I also plan on doing some experiments on timing of the chlorine injections, but that’s a little ways out. I haven’t yet hooked up my acid stenner but plan on doing that sometime this summer.
About the flow indicator (not a flowmeter), I probably wouldn’t have considered it without my recent mishap when I thought the stenner was pumping but it actually was dry running because of the crack that had developed in its suction path. In the grand scheme of things for my system (effort and costs, haha), it was an easy choice.
