Note
Press/Kfact allows for calculating flow rate from diffusers or flow stations with pressure taps using
the instruments pressure ports and Kfactors. The Kfactors are obtained from the diffuser or flow
station manufacturer. For more information, refer to
Application Note AF-114 .
Actual/Standard Setup
Choose Actual/Standard measurements and parameters in the Actual/Standard Setup menu. The
instrument measures the actual barometric pressure using an internal sensor. The temperature source
can be entered manually or taken from a probe that measures temperature (plug in probe).

Probe
The pressure based probes (pitot tube, AF probe and Velocity Matrix) need a valid temperature to
perform the standard or actual velocity or volume flow corrections. This is accomplished in the
Actual/Std
Setup menu. If no probe capable of measuring temperature (plug in probe) is connected, the Temp
Source must be set to Entered . The air temperature must then be manually inputted using the Entered
Temp setting. If the Temp Source is set to Probe, and no probe is connected, dashes (------) will appear
on the display.
For the Diffuser Flow tool (Flow from Pressure and K-factor), temperature and barometric pressure are
not used for calculating flow. Therefore, a set temperature is not required for this tool.
