* Minimum recommended flow for accurate flow readings
** Good design practice dictates the maximum flow not to exceed 5ft/sec. Suggested maximum flow is based upon Class 200 IPS plastic pipe
Maximum Distance Between Controller/Sensor Decoder and Sensor: 1000 ft/300 m
Wire: 18 AWG/1 mm, 36”/1 m leads (Ø = diameter)

Flow-Sync 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 Offset information may be entered directly. Following are K-factor and Offset values for best results with each available FCT model.
| Hunter Flow Sensor | K-Factor | Offset |
|---|---|---|
| HFSFCT100 | 0.44 | 0.39 |
| HFSFCT150 | 1.13 | 0.00 |
| HFSFCT158 | 0.92 | 1.22 |
| HFSFCT200 | 2.13 | 0.23 |
| HFSFCT208 | 1.72 | 1.70 |
| HFSFCT300 | 4.61 | 0.18 |
| HFSFCT308 | 5.87 | 1.07 |
| HFSFCT400 | 8.77 | 0.48 |
