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!

The legacy desktop program is available on a CD-ROM, or it can be downloaded from our FTP site. Please contact us for more information. If you are a registered user and need the latest database please contact us.
