Boom or Boomless Sprayer Calibration
Volume method
1. On level ground, fill sprayer tank to a known level with
water and drift agent (if using).
2. Turn on sprayer till all nozzles have output, shut off and
refill tank to desired level.
3. Measure off'/4 of an acre, marking the start and end with a
flag.
Width of boom Linear feet to
swath in feet cover 1/4 acres
2 5445
4 2723
6 1815
8 1362
10 1090
20 545
30 363
4. Drive the measured 1/4 acre with the speed that you will be
using to spray, turning on the sprayer at the starting mark
and off at the ending flag.
5. Return to the level ground that you filled the sprayer at and
carefully measure the amount of water it takes to refill to
the known level from step 1.
6. Multiply the amount from above step by 4. This is GPA
(Gallons Per Acre).
Stationary method
1. On level ground, fill sprayer tank with water and drift agent
(if using).
2. Turn on sprayer and measure spray pattern width in feet.
3. Collect liquid from each nozzle for 1 minute. Measure in
ounces.
4. Divide ounces by 128 to determine GPM (Gallons Per
Minute).
5. Determine speed (MPH) you will be using during spraying.
6. With the below formula calculate GPA(Gallons Per Acre).
GPA= GPM x 495
MPH x swath width(feet)
