Installed it this morning. Piece of cake! The only tools I used for the install were a cordless drill with a 3/8" bit and a knife to cut the tubing.
I can get full flow on the meter, with what I think is a fairly typical IG pool installation.
What do they expect you to do with those tiny cable ties? The manual says to use them to clamp the flow meter in place on a pool pipe, but it takes three of them to reach around an inch and a half PVC. Minor nitpick, I know
I'm amazed how distinct the chlorine layer is in the tank and how quickly it forms. I'm just using 6% bleach and it is very distinct. This should reinforce the idea that you shouldn't add liquid chemicals to your pool quickly or without the pump running.
Make sure you choose a spot so the lid will lift all the way. That way the bleach bottles will sit in the funnel so you can drain the last little bit.
My thinking is that I might want to do some night runs of the unit to get a feel for ppm/hour at various settings of flow so I can zero in quickly if I change pump run time for solar.
Overall, two thumbs up.
