The Sash Position approach represents a widely accepted method designed to control face velocity base on calculations

configured directly into the controller. Face velocity is controlled by calculating the flow area based on sash position and

then controlling a calibrated air valve.

Secondary air flow feedback is also possible. The Sash Position method uses polymer coated string pots, a linear airflow

valve, and a differential pressure switch to regulate face velocity.
