When the reservoir gets to a pre determined level, the PLC will control the RO unit for a Purge, and fill of the Res. The PLC will also control independent level of 4 tanks. With this PLC, there will be safety timers for maximum RO run time as well as level control is managed bu Ultrasonic non contact level sensors. Nothing to stick, no salt creep to worry about etc.
Once this is complete, I'll be making a lighting program with another PLC.

why not build the whole thing out of polymers and drive it with buried magnets |
