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 Area Manager for more information!
