Calibrating the Sprayer
When spraying with boom, sprayer must be
calibrated to ensure proper spray coverage and
to combat over-application or under-application.
The calibration process consists of three steps:
• Calculate speed of tractor.
• Determine nozzle size and consult
calibration chart for desired or instructed
gallon per acre (GPA).
• Set pressure using relief valve.
Calculating the Speed
It is important to determine what speed the
tractor will be traveling while spraying. Even if
tractor has a speedometer, it is still
recommended that speed be checked for
accuracy. Perform the following steps to
determine speed:
1. Measure a 200 or 300 foot distance on a
field or surface similar to where sprayer will
be used.
2. Drive tractor with half-full sprayer across
measured distance at a constant and
3. comfortable speed for spraying. There can
be no changes in speed while measuring
time.
4. When using a gear-driven tractor, select a
gear where PTO is at or near 540 rpm. This
is important for pump to provide adequate
pressure to sprayer when spraying.
5. Determine amount of time, in seconds, it
takes to travel the measured distance.
6. Speed can be determined by entering data
into the following equation:
7. speed (mph) = (distance (ft) x 60) / (time
(sec) x 88) or by consulting the following
table:
NOTE: If using boomless nozzles, use the
Boomless Nozzle Calibration Chart.
Useful Formulas
GPA = Gallons per Acre
GPM = Gallons per Minute
MPH = Miles per Hour
GAL/1000 sq ft = Gallons per 1000 sq ft
W = Nozzle spacing in inches
GPM Per Nozzle = GPA x MPH x W / 5940
GPM Per Nozzle = GAL/1000 sq ft x MPH x W / 136
GPA = 5940 x GPM (Per Nozzle) / MPH x W
GPA = Gallons per 1000 sq ft / 0.023
GAL/1000 sq ft = 136 x GPM (Per Nozzle) / MPH x
W
