Where: Q = Airflow Rate (cfm)
∆
P = Sensor Differential Pressure ("w.g.)
K = K-Factor Calibration Constant (standard air)
F = Amplification Factor (sensor gain)
A = Nom. Duct Area (sq. ft.)
The K-Factors tabulated in the above tables are the
airflow required to produce a 1.0" w.g. differential
pressure at the Diamond Flow Sensor.
