Flow Operations
SET UP FLOW MANAGER
Flow Manager runs simultaneous stations to reach a
programmable ow rate target. It allows the controller to
decide which stations to run, to keep total ow as close to
the pipe design capacity as possible, and shorten the overall
watering time.
Flow Manager does not require a ow sensor, but it must have
station ow values to work with. If ow learning via a sensor is
not available, approximate values may be entered manually.
Flow Manager does require one or more Flow Zones, and
requires stations to be attached to the Flow Zones in order to
function. Flow Manager and Flow Monitor can also work at the
same time, and use much of the same information in dierent
ways.
Flow Manager requires the following information to operate
correctly:
• Set up Flow Zones and set Flow Targets (Flow menu, Flow
Zones)
• Attach stations to Flow Zones (Stations, Station Setup)
• Learn or enter station ow rates (Stations, Station Setup)
• Set Controller Program Limits (Stations, Station Limits),
if desired.
FLOW ZONES
Dial to the Flow menu and select Flow Zones if they have not
already been created. The Flow Zone denes a section of
pipe and a group of stations attached to that pipe, which is
managed as a hydraulic unit.
For Flow Manager, it is only necessary to Enable Flow
Management and set the Flow Target. Check the box for
Manage Flow.
FLOW TARGET
The Flow Target box is used to set the ow rate desired for the
Flow Zone throughout irrigation. Enter the desired rate of ow
that is best for the mainline pipe diameter (recommended at
5 feet per second or 1.5 meters per second) or a preference
based on other factors.
This is the only setting necessary at the Flow Zone menu
for the Flow Manager function. Flow Manager will try to run
enough simultaneous stations to stay at or near this rate of
ow whenever there are programs available to run.
