CALCULATE THE RATE 1 AND RATE 2 CAL VALUES
Determine the application rate at which the chemical is to be sprayed, and then consult with your Raven dealer to
verify that the spray nozzles are capable of applying at that rate. To determine which spray nozzles to use with the
sprayer, the following information must be known:
With this information, calculate the volume per minute, per nozzle using the following formula:
Refer to the following chart to determine which nozzle to use based on the desired output.
FOR EXAMPLE:
Brake Point
Sets the percentage away from target rate
at which the control valve motor begins
turning at a lower rate.
0 - 9
0 = 5%
1 = 10%
9 = 90%
Dead Band
Allowable difference between the target
and actual application rate, where rate
correction is not performed.
1 - 9
1 = 1%
9 = 9%
Nominal Application Pressure PSI (kpa)
Target Application Rate GPA (lit/ha)
Target Speed MPH (km/h)
Nozzle Spacing inches (cm)
GPA (lit/ha) x MPH (km/h) x inches (cm) = GPM (lit/min)
5,940 [60,000]
Nominal Application Pressure 30 PSI (kpa)
Target Application Rate 20 GPA (lit/ha)
