One common application of control combined with feed forward control is in level control for steam drums The control strategies now used in modern industrial had their beginnings on shipboard steam propulsion When operated at low pressure it was reasonably inexpensive to make the steam
The purpose of control is to achieve greater stability of the process variable by regulating a secondary process variable in accordance with the needs of the first An essential requirement of cascaded control is that the secondary process variable be faster-responding (ie shorter lag and dead times) than the process

Classification of Centrifugal Centrifugal are classified in several ways may be classified: in terms of energy conversions (volute type and diffuser vane ring type); in terms of fluid flow through the (radial mixed flow and axial flow); as either single stage or multistage ie in
· If I use control system for level (master) and flow (slave) how can I limit the flow at certain number ie 50 m3/hr From my understanding for control system the setpoint for level is fixed while the setpoint for flow is floating to ensure level meets the setpoint Is it applicable for all control system scenarios?
