Note
: If flow device #1 has a NOMV, the system assigns the device as master valve 1 (MV1). This flow device
can monitor flow rates and automatically shut down the NOMV on a high flow condition, independent of the
state of the controller. If you want the device to provide 24x7 monitoring, you must supply power to the
device either from an external 24 VAC source or by setting the two-wire to be always on.

Press the
NEXT
button to move to the
K-Value
field. If the flow device was purchased from Baseline and is
either a PFS-series or BHM-series device, the K-value and Offset are pre-programmed into the device and will
be read and set during the Search operation.
Note
: Make sure that each flow device in the system is configured with a K-value and Offset pair or with a
pulses/gal value. These numbers are used to take the pulses generated by the flow device and turn them into
a more useable value, such as gallons per minute (or total gallons). To find these numbers, refer to the
documentation that came with the flow device.
6.
Press the
NEXT
button to move to the
Two-Wire Always On
field. If the two-wire is set to always on, it will
only turn off when the controller dial is moved to the OFF position.
Note
: Press the CLR button to return to the top menu level from a sub menu.

When you have finished making changes, turn the dial to the
Auto Run
position.
Flow Device Limits and Monthly Budget
You can set limits and budgets for each individual flow device and for the mainline that these flow devices attach
to. Refer to the procedure for setting up the mainline on page 61.
You can set the following values for each flow device on the Flow Device Limits screen:
Note
: The step-by-step procedure for configuring the flow device limits is on page 59.
•
Design Flow
– In this field, you can enter the specified gallons per
minute (GPM) for the point of connection (POC) that supplies water
through the flow device to the rest of the irrigation system. The
BaseStation 3200 uses this value to manage the number of concurrent
zones so that the water source is used as efficiently as possible. If you
set this value to zero, you cannot use this GPM amount to control zone
concurrency.
•
High Flow Limit
– The system uses the GPM value in this field as a
critical limit. When this value is greater than zero, the system
compares the limit against the measured reading from the flow device
every minute. If the flow rate reading exceeds the limit for three or four minutes in a row, the system
generates an alert.
If you set the Shut Down field to Y (yes), then programs using this POC will be stopped and corresponding
master valves (MVs) will be shut off when the flow rate exceeds the limit.
If the flow device is a Flow+NOMV type, the flow limit is programmed into the flow device. The system
monitors the high flow limit and the NOMV shuts off when the flow limit is exceeded. When a flow device is
connected to external power, the NOMV will shut off even when the controller off or powered down.
•
Unscheduled Flow Limit
– When this limit is set to greater than zero, the system monitors the flow 24x7 for
any flow that does not correspond to running programs.
When you have a NOMV, you can set this limit to allow some flow that is off schedule, such as from manual
taps or hose bibs.
If the flow exceeds the limit for several minutes, the system generates an alert. If you set the Shut Down field
to Y (yes), then the associated MVs will turn off.
