4H. FLOW CHECKING
Flow checking allows you to have the controller
compare the flow of each station during irrigation to
the learned expected flow and alert you of any
problems.
From the FLOW METER, MASTER VALVE & PUMP
SETUP screen (Figure 4.1).

This section allows you to enter the
fluctuation range for the low end of your normal
operating flow. Use the (-) and (+) entries to set the
range.
Example:
If you set the below limit at 30 gallons per minute.
and set your limit at -5/+5,
You will be alerted if the flow at the low end of the
scale fluctuates by more than 5 gallons per minute
in either direction.
That is less than 25 gpm or more than 35 gpm

From / To:
This section allows you to set the
fluctuation limits for the lower range of your medium
flowing valves. In this box you want to enter the
normal operating range of water flow. Then in the (-)
and (+) blocks enter the range of fluctuation that you
deem normal.
Example:
If you set the below limit at 30 gpm to 65 gpm.
and set your limit at -10/+10,
You will be alerted if the flow at the low end of the
scale fluctuates by more than 10 gallons per
minute in either direction.
That is less than 20 gpm or more than 75 gpm
2nd From / To:
This section allows you to set the
fluctuation limits for the high end of your medium
flowing valves. In this box you want to enter the
normal operating range of water flow. Then in the (-)
and (+) blocks enter the range of fluctuation that you
deem normal.
