2. CALIBRATION OF SPRAYER SYSTEM
A. CHOOSE AND MEASURE OFF one of the following three fixed distances:
(LONGER DISTANCES PRODUCE MORE ACCURATE RESULTS).
1. 1/4 mile = 1320 feet
2. 1/2 mile = 2640 feet
3. 1 mile = 5280 feet
B. COMPLETELY FILL the main tank and verify tank straps are tight.
C. SHUT-OFF OPTIONAL END NOZZLES using manual shut-off valve.
D. SPRAY THE CHOSEN DISTANCE using:
1. Desired ground speed within factory recommended range of 4 to 12 miles per hour (mph).
2. Desired operating pressure.
E. MEASURE the gallons of water required to completely refill the main tank.
F. CALCULATE APPLICATION RATE using correct formula for measured distance chosen:
a. For 1/4 mile:
U.S. Gallons per Acre = Measured Gallons of Water x 33
Actual Spraying Width (feet)
2. For 1/2 mile:
U.S. Gallons per Acre = Measured Gallons of Water x 16.5
Actual Spraying Width (feet)
3. For 1 mile:
U.S. Gallons per Acre = Measured Gallons of Water x 8.25
Actual Spraying Width (feet)
G. EXAMPLE
28 gallons of water was required to completely refill the main tank of a 90’-0” sprayer over a
1/2 mile distance.
28 gallons of Water x 16.5 = 5.1 U.S. Gallons per Acre
90 Feet
