4. Crop Coefficients
This setting is used to adjust ET for a specific type of
crop at different periods throughout the year. If you
do not want ET to be modified, leave the selection
set at NO (Figure 5.24)
From the WEATHER SETUP screen (Figure 5.2).
1. Press the CROP COEFFICIENTS
Menu key.

This will allow you the option of entering Crop
Coefficient values for each month of the year, on
each program in the controller. You must be familiar
with crop coefficients to use this feature.

CAUTION:
When using Daily ET mode you will have to set each
Stations flow rate, Precipitation rate, and square
footage area for every program using Daily ET. The
following instructions cover how to set up station
flow rates whether or not you have a flow meter
installed.
NO FLOW METER INSTALLED D
5. Station flow rates without a flow meter
present:
There are two methods to determine station flow
rates if a Calsense flow meter is not installed on the
system. The following describes each method
•
How to calculate Station Flow rates
Using Manufacturer’s Published data:
With the first method, you use a manufacturer’s
catalog which has the flow rates (gpm) listed for the
type heads, and nozzle sizes on the system you are
calculating. Simply total the flow rates for all of the
nozzles on the station.
Example:
A station has 8 half-circle pop-ups with a flow rate of
2 GPM each, 3 full circle pop-ups at 4 GPM each
and 4 quarter circle pop-up heads at 1 GPM each.
The station’s flow rate would be calculated as
follows.
8 heads x 2 GPM = 16 GPM
3 heads x 4 GPM = 12 GPM
2 heads x 1 GPM = 2 GPM
Total flow = 30 GPM
