WFS Calibration Factors
Hunter controllers allow selection of the correct
pipe size by FCT model number. No further
calibration is needed.
If “Other” is selected, K-factor and Oset
information may be entered directly. Following
are K-factor and Oset values for best results
with each available FCT model.
