RATE OF DISCHARGE
54
* Divide by 10 to get 1 gallon per acre rate
** At a rate of 10 gallons per acre
The measured flow rate should be the same as
the flow rate shown on the chart below. The chart
shows rate of discharge in gallons per minute for
various field speeds and row spacings to apply 10
gallons per acre.*
If the measured flow rate is not the same as
that on the calibration tube’s chart, consult the
trouble shooting guide in the service manual for the
spray system’s monitor.
All nozzles should be spraying at about the
same flow rate. If one drives the sprayer at the
proper speed and maintains the right pressure
setting while spraying, the desired gallons per acre
will be applied.
