Capture Hood
For measuring flow from grilles and diffusers.
Pressure Only For measuring static or differential pressures.
Pitot Tube Flow and velocity measurements inside ductwork.
AF (Air Flow) Probe
– Straight Pitot
Probe Flow and velocity measurements inside ductwork. Can also be used for face
velocity measurements.
Velocity Matrix
For area-averaged multi-point face velocity measurements.
Flow/K-factor Used to calculate flow from diffusers equipped with differential pressure taps.
The flow through the diffuser can be calculated by multiplying the square root
of the pressure times a user entered k-factor obtained from the diffuser
manufacturer.
Note : The K-factor is entered in the Flow Setup Screen.
None Disables pressure sensor and zeroing valves. Select None when using
thermoanemometer probes when differential pressure measurements are not
required.
