PLC auto dosing

[kysard1]

Is part of this controller to have stationary probes in the tanks with a closed loop feedback for controlling things like pH, alkalinity, salinity. We do this at work, its a simple program

Can you get your hands for these type of probes?

[kysard1]

You can muy them on the internet, the trick is the PLC programing

[Jack04]

plc programing is no prob, just find the program to program ladder logic and presto, a little mor involved than that but i learned ladderlogic last winter to program a plc, and i did fine, but the cost of plc, program and such might be high

I own the PLCs I need a solution for the probes. Kysard1, can you point me to the web pages you are refering to please.
