📘 Screen: Spray Nozzle
The Spray Nozzle screen registers the nozzles used on the farm's sprayers, with their type, model, angle, and the relationship between pressure and flow rate. This setup standardizes the values used in application calculations, so each operator doesn't work with a different number.
📍 Location in the system
Menu: Operations > Spray Nozzle
🧩 Main function
Maintain the list of nozzles available for use in application activities. The nozzle is chosen in the spray volume settings of the Work Order/Activity Type, together with the spray volume, the tank capacity, and the hectares per tank.
📝 Setup fields
| Field | Description |
|---|---|
| Name/Description | Required. Nozzle identification. |
| Type | Required. Mesh, Cone, Rotary atomizer, or Hydraulic nozzle. |
| Code | Internal identifier. |
| Model | Nozzle model, according to the manufacturer. |
| Angle | Spray fan angle. |
| Active | Defines whether the nozzle is available for use. |
💧 Pressure and output
Each nozzle accepts several records linking the working pressure (PSI) to the corresponding output per minute. This is the nozzle curve: the same part delivers different flow rates depending on the pressure applied.
Entering these pairs is what lets the application calculation use the right value for the pressure at which the sprayer actually works.
- The activity type's spray volume settings point to a real nozzle, not to a loose value
- The flow rate used in the calculation matches the equipment's working pressure
- The whole farm works with the same application parameters
❓ Frequently asked questions
Where is the nozzle used after it's set up?
In the spray volume settings of the Work Order/Activity Type, which apply to crop protection spraying activities. Each spray volume setting points to a nozzle.
Which nozzle types does the system accept?
Four: Mesh, Cone, Rotary atomizer, and Hydraulic nozzle. The type is required.
Why set up more than one pressure for the same nozzle?
Because the nozzle's flow rate changes with pressure. By recording the pairs of pressure (PSI) and output per minute, the application calculation uses the value that matches the pressure at which the sprayer is working.
I can't delete a nozzle. What should I do?
When it has already been used in a setting or work order, the system does not allow deleting it. Uncheck the Active field: the nozzle stops showing up in the lists and the old records stay intact.
