Operation For Vane Type Anemometers: 1- Remove the chamber door. Open the clamp in the adjustable mounting block by turning the wheel. 2- Place the vane propeller inside the chamber. Make sure it is in the center of the chamber. 3- Place the vane window door. - Page 11 Operation Example 1: An FMA-904 Hot wire anemometer is being checked in the Wind Tunnel at 2.5 m/s (492 FPM) air speed. The Environmental conditions are: Barometric Pressure = 27.88 inches of Hg Ambient Temperature = 80 ºF The FMA-904 measures 442 FPM. Calculate the actual air speed: Actual Air speed = Measured Value (Average value over one minute time) x K1 x K2 K1 = (29.92/P) x (460 + T)/530...
