7.2. Measuring Velocity
The Meter uses standard ambient conditions (temperature =21.1 °C/70 °F, barometric pressure =
14.7 PSI / 1013 mbar), to approximate actual velocity and flow.
The primary display number is air velocity, the device measures air velocity, and it features 5
selectable units of velocity measure: m/s, ft/min, km/h, MPH, knots.
1. Press to enter Velocity mode and press to select unit.
2. Connect the hoses to the pitot tube to the Meter. The “Input (+)” pressure port on the Meter
connects to the white hose from the total pressure connection of the pitot tube. The “Ref (-)”
pressure port on the Meter connects to the black hose from the static pressure connection of
the pitot tube. the tubing open to ambient conditions press and hold for 2 seconds to
