Hello,
I have four metering pumps that widraw neat sodium hypochlorite from bulk storage tanks. Pumps speed will be paced off of the plant flow signal while the pump stroke length will be paced off the total residual chlorine.
I will control the pump's speed and stroke length in the PLC using PID controller. I am confused which parameters (for PV and SP) will be used in speed control. I have the following signals: effluent flow(plant flow), total residual chorine and total flow(discharge flow,the flowmeter after the metering pumps).
Please advice..
Thanks & regards.
