Results from three years and locations indicated that collectors with a 10-cm opening may not provide reliable irrigation depth data under fixed-plate (FP) sprinkler packages that produce distinct streams of water. Collectors with 15-cm diameter openings provided acceptable results under the FP sprinkler packages. The 10-cm opening collectors accurately measured both irrigation depth and uniformity under spinning plate (SP) and wobbling-plate (WP) sprinkler irrigation packages that produced smaller, more evenly distributed irrigation droplets with no distinct streams or jets.
