Advanced Plate Design
The plates of the R3000 Rotator are specifically engineered for high performance.
The Up-Top Blue Plate for the R3000 Rotator utilizes 4 low-trajectory streams for excellent coverage and wind-fighting ability at higher pressures.
The Up-Top White Plate for the R3000 Rotator features multi-trajectory streams for superior performance above the canopy with the added benefit of fitting into a lower pressure range.
The Green Plate for the R3000 Rotator utilizes 4 low-trajectory streams for maximum coverage and wind-fighting ability across a wide pressure range.
The Red Plate for the R3000 Rotator features 6 streams with low stream height for greater droplet breakup and the benefit of a gentle application with uniform coverage.
The premiere plate for tall growing crops like corn – the Orange Plate for the R3000 Rotator features outstanding performance with multi-trajectory, highly-engineered streams. The streams penetrate the canopy and provide maximum coverage with high uniformity.
The premiere plate for low-growing, high-value crops such as potatoes – the Brown Plate for the R3000 Rotator utilizes 10 multi-trajectory streams that provide maximum uniformity and superior performance.
Sprinkler Irrigation Uniformity is how evenly a set of sprinklers delivers water over the soil within the sprinkler’s effective throw diameters. The higher the uniformity, the more even the water application is, and results in all of the plants receiving very similar amounts of water. Lower uniformity numbers create more areas which are too wet or too dry.
Consideration of a sprinkler’s throw diameter is essential. The larger the throw diameter, the lower the application rate at a given flow, insuring less runoff and lower erosion rates. A good design will match the application rate of the sprinkler with the infiltration rate of the soil. The throw diameter is also critical in determining spacing requirements. Generally, sprinklers need to overlap 150% to assure uniform application. Additional overlap can help raise uniformity further.
Stream height is the peak height above the sprinkler of the major droplets emitted from a level sprinkler under no wind conditions. Higher stream heights are effective for achieving longer throw diameters but can suffer from evaporation loss and distortion in areas of windy conditions. Higher stream heights require mounting height considerations to avoid issues with structure interference. Lower stream heights are more effective in delivering water in windy conditions with less evaporation loss but sacrifice effective throw diameters.
Uniformity values indicate the lowest predicted Christiansen's Uniformity, CU, at any spacing within Nelson Irrigation Corporation’s recommended limits of the sprinkler at the indicated crop clearance. High values indicate that the product can be used with relative safety throughout the spacing range. Application of the product in conditions for which the tabulated values are lower may require additional analysis to determine the most advantageous spacing. Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, or application rate. Height values shown indicate the maximum height of major droplets emitted from a level sprinkler under no wind conditions. Sprinklers should be mounted at least this far below the pivot structure to minimize wetting of the structure, but they may be mounted slightly higher without significantly affecting the sprinkler pattern. Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, or application rate. Stated throw performance at nozzle pressure. Tested at 1250 feet above sea level. Sprinkler performance data have been obtained under ideal test conditions and may be adversely affected by wind, poor hydraulic entrance conditions, or other factors. Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, or application rate.
