Edzi, it would be speculation. You can control systems to give you various inputs/outputs. You can control PH vlaues, flow rates, pressure etc. You need a process transmitter to give you a true actual value, Your programmable logic will have the desired value, from this it will give an error/deviation signal along will a lot of other permissive that must be met (Ladder logic).
Operators will put in a desired value, the logic will measure it against you actual value to give an error signal. This value will be used to adjust the process. this signal can be slow to ramp up/down giving stability or quick to adjust but becoming more precise, but that can be unstable. There can be hundred of transmitters feeding into the logic, all affecting various parts of the process. Inverters for motor speed control/pump pressures.
Lets hope it a standardised unit that can be set up on site with various perameters set to achieve different outputs from various feedstocks/Grades.
