Pneumatic Flow PID Control System

What is Pneumatic Flow Rate PID Control System?

The digital data from the flow meter is shared with the controller via cable. Here the controller decides whether the flow rate is higher or lower than the set value. If the flow rate is lower than the set value, the controller sends a signal to the positioner to open. If the flow rate is higher than the set value, the controller sends a signal to the positioner for throttling. Until the flow rate values set on the controller are reached.
