Distribution Uniformity

These figures are achieved at operating pressures of 4 bar in calm conditions at a uniform post spacings as shown of 40m on flat contour. (note: currently using 41m)

Test 2 = PF 24 with 12mm bird cage nozzle with thrusting bias.

• Sprinkler operating at 4BAR.
• Departure velocity is approximately 120 km per hour.
• Throw radius 33 meters, i.e. 66 meters diameter in calm conditions.
• Distribution uniformity (DU) at 92.65%

Average application rate = 8.98mm/hour at 4 bar.
