when programming the flow device, or when referring to the flow device from other menus.

To remove a two-wire device, you must physically diconnect it from the
two-wire and then perform a Search operation from the device specific
menu. This means a biSensor can only be removed by doing a search from
the biSensor menu, etc..

Each flow device in the system needs to be 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, gallons per minute (or total gallons). These numbers are
supplied by the manufacturer of the flow
device. If the flow device was purchased from
Baseline, and is either a PFS-series or BHM-
series device then these values are pre-
programmed into the device and will be read
and set when the Search operation is done. In
the screen to the right the Pulses/Gal has been
set to 20.0

The flow device in this example also has a built-
in Normally Open Master Valve (NOMV)
decoder. Because this is flow device #1, the
NOMV can be used if desired, but is only
available as MV1. This make the paring from flow device #1 to MV1 automaticly. 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. To provide 24x7 monitoring, the device must be
powered up and can be either powered externally with a 24 VAC power or by setting the two-
wire to be always power on. If the two-wire is set to always on, it will only turn off when the dial
is moved to the OFF position.

Use the CLR key to return to the top menu level from a sub menu.

Flow Device Limits & Budget

There are limits and budgets that can be set both
for each individual flow device, and for the
mainline that these flow devices attach to (more
on mainlines in the next section).

Turning the dial to the Flow Menu, selecting the
Flow Device Limits menu and pressing ENTR will
show the programming screen like the one to the
right. There are four values that can be set for
each flow device, with three of these having the
option to shut down watering to some degree if
the limit is exceeded. These values will now be
explained.

Design Flow

This is the specified design flow for the point of connection (POC) that supplies water through
the flow device to the rest of the irrigation system. This value is one factor when a system is
designed, and can be used to manage the number of concurrent zones so that the water source
