My pool is controlled with a homebuild system for turning on pump, SWG, heatpump, lights and measuring temperatures.
It is all working perfectly, but I want to take the next step : measure pH and chlorine. The Atlas Scientific sensors (pH and ORP) seem to be good sensors for this setup.
I have zero CYA in my pool, and as I understand this would be the best for ORP meassurements. My SWG cell is capable of producing 25 gram chlorine gas, raising my FC with 0.6
If I would read the ORP frequent (during pumphours), I should be able to correct my FC by turning the cell on or off, correct? My SWG is set to 100% and is only turned on during pumphours according to a schedule, you could say the SQG is independent of pumphours.
The ORP sensor can handle up to 100 psi pressure, bu I'm not sure if it needs to be submerged all the time? The pH sensor (as far as I'm aware of) should be submerged to prevent dry out. To prevent dry out of at least the pH probe, I would make some lowering in a running pipe so there will allways be water in that part of plumbing?
Any ideas, thoughts? Am I totally wrong in my plans?
