Sprinkler coverage defined by the project.
Water is distributed by sprinklers over the area. Sizing combines reach, spacing, pressure and field conditions to organize the application.

Covering the area requires considering the distribution of the jets.
Positioning a sprinkler does not guarantee that the entire area will receive the intended application. The combination of range and spacing, wind conditions and available pressure need to be evaluated. The project also considers how water infiltrates the soil and how the sectors will be operated.
- Distribution in the area
- Shape, limits, obstacles and spacing between sprinklers guide the coverage and overlap of the jets.
- Wind and pressure
- Local conditions and work pressure influence distribution. Pumping and piping need to meet the expected sectors.
- Soil and routine
- The application must be compatible with soil infiltration. Schedules and duration are defined based on the needs of the crop and operation.
Check the application in addition to turning on the system.
Inspect sprinkler nozzles, pressure and operation. Observe areas with uneven application or surface runoff and record operating conditions. A field assessment can guide spacing, component, or programming corrections.
What to check in the sprinkler project.
A sprinkler proposal needs to relate the chosen sprinkler and nozzle to the working pressure, flow rate, spacing and sectors served. The range reported in the catalog does not summarize the distribution in the area: wind, jet overlap and soil infiltration are also included in the assessment.
If an installation already exists, take the sprinkler model, the identification of the nozzles, the design of the sectors and the available measurements. In the field assessment, the pressure must be observed with the sector in operation; Water distribution can be checked with collectors. This data helps you discuss the scope of suitability before choosing new equipment.
Questions about sprinkling.
How to define the spacing between sprinklers?
Range, pressure, wind and geometry of the area need to be considered together. Spacing results from sizing and assessment of local conditions.
Is it possible to improve an existing sprinkler?
The assessment can compare current operation with the required coverage, inspecting pressure, nozzles, pipes and sectors. The adjustments depend on the diagnosis of the area.
