The VAV velocity field displays calculated FPM from the velocity pressure derived from the pressure input. The pressure sensor is previously setup and calibrated to be accurate.

If the VAV box is not selected, the value is zero. Enter a valid VAV box K factor entry, downloaded to the UVM, for the specific flow probe on the VAV box.

The UVM calculates the velocity value. The UVM does this by multiplying the square root of the flow pressure from the pressure input by the K factor, if the VAV Box is checked.
