Broadcast Nozzle Calculator Instructions:
Input the Application Rate, Speed, and Nozzle Spacing to calculate the flow rate and see the nozzles that meet those flow rate requirements. Each colored square indicates a nozzle that will work for your requirements and shows the droplet spectrum that will be produced by that nozzle at that PSI. You can click on the droplet spectrum to see a traditional tabulation chart for that particular nozzle.
All droplet data follows the current ANSI/ASABE S572.3 droplet size classification standard. Testing was completed by a third-party lab at the University of Nebraska Low Speed Wind Tunnel. Because the testing method and the industry standard have both advanced, many droplet category callouts in our nozzle charts have changed compared to older published data.
Droplet size and ranges are calculated differently for wind tunnel testing. Driftable fines are reduced by the testing method, but wind shear reduces size of all other droplets. Also the droplet spectrum is set by reference nozzles that are tested with each batch, giving each run a slightly different droplet category ranges. This is a close aproximation of what those ranges usually look like:
- Very Fine Droplet Size: <141 microns
- Fine Droplet Size: 142-260 microns
- Medium Droplet Size: 261-390 microns
- Coarse Droplet Size: 391-470 microns
- Very Coarse Droplet Size: 471-630 microns
- Extremely Coarse Droplet Size: 631-780 microns
- Ultra Coarse Droplet Size: >781 microns
As droplet size increases, coverage and drift potential go down. Using DualFan nozzles with larger droplets can help balance the drift reduction of larger droplets with increased coverage of the spray pattern.
Application rate, usually determined by the label of the product you are applying and the amount of water used as a carrying agent.
Input the cruising speed that you will be at most of the time. Automatic rate adjustment systems will adjust the pressure of the boom depending on variations in speed.
The distance between nozzles on the spray rig.
Advanced Options:
Select water or a denser tank mix to adjust the required PSI for specific gravity. Denser fertilizer mixes require more pressure to produce the same nozzle flow.
Filter results by spray pattern, such as 110° flat fan, DualFan, hollow cone, off center, RowFan, or SpotFan.
Filter results by ASABE droplet category. The dropdown uses the same droplet colors shown in the results.
Choose whether recommendation cards are grouped by nozzle type or by nozzle size. Group by type is useful for comparing sizes within a product family. Group by size is useful when PSI is the main decision point.
Tip size, note that these are commonly listed as 02, 03, 04. The number is a description of the orifice size and flow rate. For example, an 03 nozzle flows 0.3 US gallons of water per minute (gpm) at 40 psi.
Results Fields:

Beluga HoseDrop Calculator Instructions:
Input the Application Rate, Speed, and Nozzle Spacing to calculate the flow rate and see the nozzles that meet those flow rate requirements. Select the number of Beluga Heads you have on each HoseDrop, and the required per nozzle flow rate will automatically be adjusted. Each Beluga Head has 2 nozzle tips. Select an Overhead nozzle size when standard nozzles are spraying from the unused nozzle bodies at the same time as the Beluga HoseDrops. Beluga HoseDrop recommendations are limited to a total of 4 gpm through the HoseDrop. You can click on a result to see a traditional tabulation chart and nozzle information for that particular nozzle.

Each system has different pressure drops from the Pump PSI to the Tip PSI for each nozzle size and pressure combination.
In many cases, the systems are listed by the nozzle solenoid manufacturer, and some of those systems are marketed under different names. For instance, the Case AimCommand FLEX II, New Holland/Miller Intelispray 2, and Raven Hawkeye II systems all use the same nozzle body solenoids.
Application rate, usually determined by the label of the product you are applying and the amount of water used as a carrying agent.

PWM Nozzle Detail Instructions:
These charts show a speed range for operating a specific size nozzle at a given pressure. The percents across the top indicate Duty Cycle, and the numbers in the body of the chart indicate the speed in miles per hour.
The droplet data on the charts provided here reflect the adjusted droplet spectrum, based on calculated nozzle pressure, and not boom pressure.
If data on the chart is not shown, it means that the selected PWM system does not have published data for this pressure range, or that it is unable to overcome the loss in pressure from the solenoid to supply the required pressure to the nozzle.
Nozzle type information, part number, size, mesh, pressure range, spray pattern, sizes available, and description are shown at the top of each tip detail page.
Nozzle Detail Instructions:
To use a traditional tabulation chart, note that nozzle pressures and flow rates are shown on the left and sprayer speeds are shown across the top. The body of the table contains application rates in gallons per acre.
Use the speed arrows in the first and last speed headings to shift the speed range slower or faster.
