Sprayer Calibration
Nozzle Flow Rate (l/min)
=
Speed (km/hr) x Swath Width (m) x Application
Rate (l/ha) ÷ 600 ÷ Number of nozzles
...... x ..... x ..... ÷ 600 ÷ .......
= .......... l/min for each nozzle
Step 5
Fit Selected Nozzles to Boom
Nozzle Type: ...................................................
Nozzle Size: ...................................................
Nozzle Colour: ...............................................
Step 6
Check Nozzle Accuracy & Determine Nozzle
Output
Thoroughly check nozzles & test the actual output of
each nozzle.
• Pressure Setting: ..........................................
• Individual Nozzle Outputs: ...........................
.........................................................................
.........................................................................
• Sum of Nozzle Outputs: ...............................
Step 7
Calculate Application Rate
The spray Controller automatically calculates and
shows the rate of application.
Application Rate (l/ha)
=
Spray Output (l/min) x 600 ÷ Speed (km/hr) x
Swath Width (m)
[......... x 600] ÷ [........ x .........]
= ................
Step 1
Check the Sprayer is in Good Working Or der
Step 2
Determine Actual Speed of Travel
Follow Instructions on page 60 (Pinto Calibration
page).

Speed in Km/h
Step 3
Measure Boom Widths
Boom section 1: .............................................
Boom section 2: .............................................
Boom section 3: .............................................
Boom section 4: .............................................
Boom section 5: .............................................
Boom section 6: .............................................
Step 4
Select Nozzle Type & Size
• Chemical: ......................................................
• Type of Nozzle: .............................................
• Pressure Setting: .........................................
• Travel speed (km/hr): ....................................
• Total number of nozzles to be used .............
Step 8
If Tested Application is Not Satisfactory - Make
Changes & Repeat Procedure
