They are set-and-move systems which are stationary for eight 12 or 24 hour sets. Nelson Impact sprinklers model F33 and F33S with Nelson 3FCN nozzles have been a long-standing reliable component of a good wheel line. Flow control nozzles provide a constant flow rate over a wide range of pressure and should be used when pressure ranges exceed 10% along the wheel line. The R2000WF can also be adapted for use on wheel lines if the spacing is 40 x 50' or closer. The R2000WF provides better uniformity than impact sprinklers and can be combined with the Nelson Mini Regulator to lock in flow and uniformity. New design technologies have enabled the development of highly uniform sprinklers such as the R2000WF; however any sprinkler can provide poor coverage if it is not properly spaced. Have a uniformity analysis completed before you finalize your spacing, pressure and sprinkler decisions. The Nelson Overlap Software is able to provide you with the information you need to get a highly uniform system at a reasonable cost.
