The Model AFS–DSS is a general purpose airflow proving switch designed for VAC HVAC and Energy Manage-ment applications where dual manual re-set switches with SPST contacts are needed. It may be used to sense posi-tive, negative, or differential air pressure. General Description Operation The plated housing contains a dia-. (T+) x ss DIFFERENTIAL PRESSURE EQUATIONS 2. 3. Any Liquid AP (in. WC) Steam or Any Gas x D4 x Q2 K2 x D4 x p x , x x (T+) K2 x x P x 16, + OF + OF AP (in. Any Gas AP (in. WC) AP = Differential pressure expressed in inches of water column. Flow expressed in GPM, SCFM or PPH as shown in equation. Simple and quick, the Air Meter is popular for servicing air conditioning, heating and ventilating equipment. Direct reading velocity and static pressure scales — both low and high ranges — show supply and return grille velocities, furnace draft, pressure drop across filters, etc.
