Minimum Flow
The purpose of this calibration parameter is to set the minimum
recommended flow rate for the spray boom and nozzles. Once set, the
system will prevent the actual flow rate from going below the
recommended minimum rating. You may set a minimum flow rate for
each target rate.
Calculating minimum flow value:
Determine from your tip chart what your nozzle’s minimum gallon per
minute (liters per minute) rating is at their minimum recommended
pressure. Do not use the gallon per minute of your actual application
rate. For example, if the minimum flow rate per nozzle is .22 GPM at
their minimum pressure and your spray boom has 20 nozzles (all
sections), the minimum flow value is 4.4 (.22 x 20 = 4.4). The system
will not apply at a rate lower than this value when spraying in AUTO.
Entering minimum flow values:
Each target rate may have a different setting for minimum flow. Press
the RATE 1 button. The lower right portion of the display will show the
minimum flow value. Use the ADJUST switch to adjust the displayed
value to the calculated minimum flow rate value for the nozzles used for
Rate 1.
Repeat the procedure for RATE 2 and 3. If the same nozzles are being
used for Rate 2 and Rate 3, enter the same minimum flow value for
those target rates. If different nozzles are being used, refer to nozzle
manufacturer’s Tip Chart.
