Hello everyone
I need some suggestion from you. We are controlling the flow of water in one of application. Our problem is the set point is fluctuating and due to this the valve is continued hunting and hence the flow is also fluctuating. Our requirement is not very critical that the flow should be exactly same as setpoint +/- 5 to 10% error is acceptable. Any ideas , how to tackle it.
Note: We tried filter in PLC for the input signal, tried to adjust damping the valve. But the results are not desirable.
