Dear Forum Members,
As we have water treatment plant, where we has to control the water flow to the buffer tank.
The water flow has to be controled by Flow control valve by using PID Controller and Flow indicating Transmitter.
According to the water flow rate we has to control four Chemical dosing Pumps with the set PPM, which will be set by the operatore either by potentimeter or digital Counter.
The four Chemical Dosing pumps were variable speed driven AC Drives , which can accept either 4 - 20 ma signal or 0-10 V signal.
Once the flow of the water changes, the chemical doing pump dosing has to be change to suit the operators set PPM.
i need to built the control system as said above.
I request the forum memers to share their experience and advises.
Thanks & Best Regards,
Ravindra
