Setup and Tuning

Before proceeding, it would be beneficial to qualify and quantify the terms you will
encounter in the setup and tuning of the control system.
Proportional Control (Gain),
P
The term on the BW500 adjusts the control output based on the difference between the
set point and the measured flow rate. A higher
and faster to react to changes or disturbances. If set too high, the BW500 becomes less
stable, and more susceptible to oscillations in the control output.
