Using PD/PDF tuning to get the best performance out of your Alicat flow or pressure controller
You can adjust the PID settings of your Alicat mass flow controller or pressure controller to change how it responds to the setpoints you command. Before you get started, learn what PID tuning is and how each variable (P, D and I) affects the performance of your controller.
The PID settings for your Alicat controller dictate how quickly and precisely your controller reaches its setpoint, with P controlling the power applied to the valve and D acting as a damper, so as to not overshoot your setpoint. Your instrument should be tuned for your application, but if your application changes, our instruments are designed to adjust without having to send it back for factory reconfiguration.
