Flow velocity measurement
WebThe Fluke 922 converts velocity pressure to velocity automatically when in Velocity mode. In Flow Volume mode, the 922 will prompt for duct geometry and dimensions in order to display air flow (cfm) directly in real time. The 922 velocity and air flow calculations are based on standard air at 29.92" hg at 70 °F. Tips
