Working With Flow-Sync
Hunter flow-capable controllers are designed
to measure and record actual flow, shut off
irrigation when a high flow condition occurs, and
identify which stations caused the condition.
The controller’s Learn mode samples each station
individually, and learns a typical flow for each
station in the system. During actual irrigation,
the flow can be observed at the controller. Actual
flows are recorded and stored in the controller
facepack. The ACC or I-Core controller will also
compare actual flows to the estimated total of all
active stations, to see if there is an unacceptable
difference, indicating a leak or break.
Consult the controller documentation closely for
setup and operation of flow monitoring. It is
vital to set the correct pipe size, so that the
controller interprets the flow data correctly. It is
also important to set adequate overage amounts
(minimum is 15% over normal) and delays
(default is one minute) to prevent false alarms.
