Example #2
(If water meter units are in cubic feet or CF):
The starting meter reading is 9,975 CF. After 3
minutes, the ending meter reading is 10,003 CF.
The flow rate is be calculated as follows:
10,003 CF - 9,975 CF = 28 CF
28 CF x 7.48 gallons = 209.4 gallons
(1 CF = 7.48 gallons)
209.4 gallons ÷ 3 minutes = 69.8 gpm
Example #3
(if water meter units are in hundreds of cubic feet or
HCF):
The starting meter reading is 12,321 HCF. After 3
minutes, the ending meter reading is 12,321.25
HCF. The flow rate is calculated as follows:
12,321.25 HCF – 12,321.00 HCF = 0.25 HCF
0.25 HCF x 748 gallons = 187 gallons
(1 HCF = 748 gallons)
187 gallons ÷ 3 minutes = 62.3 gpm

Last Min:
This is the amount of time last irrigated on
this station prior to selecting the use of Daily ET.
Estimated Mins: This is the total estimated minutes
for this station using Daily ET, (calculated
automatically).
% of ET: This value can be adjusted to increase or
decrease the amount of estimated time on a station
based on percentage of ET.
Expected Flow: This is the station expected flow
rate. You can either learn the expected flow rate
(See Section 4 Learn Expecteds), or set the flow
rate number yourself.
Area: This is the amount of area in square feet that
the heads assigned to this station encompass.
Precip: This entry is the precipitation rate for all of
the heads assigned to this valve / station and is
calculated automatically by using the flow rate and
area square footage.

5F. BUDGET
The Budget feature of the controller allows you to
compare actual water usage with a water budget
that has been programmed into the controller by the
user. The user will be alerted whenever the water
usage exceeds the budget. Once the budget feature
has been enabled, there will be three budget options
to choose from:
• Directly enter the monthly budgets.
• Automatically calculate the budget amount
using the total square footage and your City
ET.(see Section 5H. ET State / County /
City).
• Enter a yearly budget and have the
controller divide it among the months using
