Even Coverage Test

HOW THE DISTRIBUTION UNIFORMITY TEST WORKS:
Distribution Uniformity—or DU—is a measure of how evenly water is applied to a zone. To calculate DU, the Center for Irrigation Technology set up a grid of catch-cans. After running the sprays for 10 minutes, they recorded the water in each can. The more consistent the
amounts of water across the grid, the higher the nozzle’s DU—and the more efficient the nozzle.

HOW THE SCHEDULING COEFFICIENT TEST WORKS:
To measure SC, the Center for Irrigation Technology recorded how long it took Rain Bird nozzles and competitive nozzles to adequately water an area. Competitive nozzles took up to 16 minutes to finish watering. Meanwhile, Rain Bird nozzles were done watering after just 12 minutes - that’s a 30% savings in valuable time, water and money.

HELPING YOU STAY AHEAD OF SCHEDULE
What’s the bottom line? By offering uniform coverage and shrinking watering windows, Rain Bird nozzles save your customers time, water and money. And that can help you expand your business.
