6.1 Calibration (Ounce Method)
If you do not wish to use the calibration kit method, the following
method may be used. All you need is a tape measure, stop watch and
a container that accurately measures U.S. fluid ounces.
1. Fill the sprayer tank approximately half full with clean water.
2. Set up two stakes, 204 ft. apart in actual spraying conditions.
3. While driving at spraying speed, note the length of time required to
drive 204 ft. Repeat several times and take the average of the times
recorded.
4. With the sprayer operating at intended spraying pressure, collect the
output from one nozzle for the length of time determined in step 3.
The number of U.S. fluid ounces will exactly measure the application
rate.
e.g. 15 U.S. fluid ounces = 15 U.S. gallons per acre
NOTE: This method only works if the nozzle spacing is 20”.
For conversion to Imperial gallons per acre, multiply U.S. GPA x .833
For conversion to liters per hectare, multiply U.S. GPA x 9.34
For conversion to liters per acre, multiply U.S. GPA x 3.78
