4.11 Boom Sprayer Calibration (Use Clean Water)

Step 1. Check your tractor/sprayer speed

Your tractor sprayer speed:

Step 2. Record the inputs

Step 3. Calculate the required nozzle output.

Step 4. Operate the sprayer

Set the correct pressure at the gauge using the pressure regulating valve.

Collect and measure the output of each nozzle for one minute.

The output of each nozzle should be the approximately the same as calculated in Step 3 above. Remember 128 fl. oz. in one gallon. If output has been calculated at 0.27 GPM then output is 128 multiplied by 0.27 = 34.5 fl. oz. in one minute.

Replace all nozzle tips that are more than 10% inaccurate.
