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. This software is available on a CD-ROM, or it can be downloaded from our FTP site. Please contact us for more information.
