Overlap is a software program capable of analyzing the theoretical uniformity of permanent or solid set sprinkler spacing. Select a specific sprinkler model configuration and spacing criteria, and the software will calculate the following:

  • Precipitation Rate
  • Christiansen's Coefficient of Uniformity (CU)
  • Distribution Uniformity (DU)
  • Scheduling Coefficient (SC)

Overlap also allows you to graphically depict and chart theoretical performance for comparative purposes. Update to Overlap Pro! Contact your Nelson Territory Manager for more information!

Sprinkler performance data have been obtained under ideal test conditions and may be adversely affected by wind, poor hydraulic entrance conditions, or other factors. Published radius and diameter of throw performance are at nozzle pressure when tested at 1,250 feet above sea level. Your results may differ from the test data results obtained by Nelson Irrigation Corporation and Nelson Irrigation Corporation makes no representation regarding droplet conditions, uniformity, application rate, or fitness for a particular purpose.
