i am working on a project Water Blending & Treatment Plant and new to this process. I have queries as>>>
1. What is metering pump.
2. For metering pump there are two parameters.
a. Speed Reference.
b. Stroke Length.
Speed reference is for controlling Flow rate & Stroke Length is used for control PH level.
* How to use these two parameters for controlling the metering pump output.
Means which PID controller two use>>>
Cascaded or Feed Forward , Ratio Controller.
I am a bit confused plz help me out on this>>>>
Any sample program would be very much beneficial.
Thanks in advance.........
