R.I.P.
Here is my current tank/automation project. This tank will be used to feed the kalk reactor. Its a 4 gallon acrylic tank with two float switches. The floats activate a latched relay that allow the tank to drain down before it refills, this saves on ro membranes. Each time the tank fills it counts 1 and displays the fill count on a lcd counter display. The same counter trigger will trigger counter 1 in the automation controller program. When the counter reaches a preset number the system will shut down and will require a reset. This is a visual indicator that its time to change the rodi filters. Eventually the shut down will be tied into the TDS which will also shut down the system in event there is a membrane failure.
