Hi, I have a cascade loop for dump control on a vessel. Level is the master and flow control for the dump valve is the slave.
The problem I have is the liquids meter does not read very good from 0-100 m3/hr or 0-5% open on the valve. I want to know if there is a way I can setup the controllers so that if the level controller is calling for 0-100 m3/hr flow the flow controller keeps the valve closed, and anything over 100m3/hr the valve will initially open to 5% and then apply P&ID control from there.
Thanks
