Allen Bradley PLC 5
What operations wants to do is as the Oil Flow rate (0-3000 m3/d) increases more chemical is injected into the flow line, chemical pump can flow between 0-950 Liters/d
How could I do PID control using these 2 parameters?
-The oil flow rate would be the process variable
-The chemical injection pump would be the controlled variable.
What would be the set point if both flows are of different ranges? There is no dedicated set point to try and maintain. Just as the oil flow increases inject more chemical. Tuning will need to be done to get the correct ratio.
Thanks so much!
