There are several factors influence the range of complete fluidic sprinkler. They are inlet press, sprinkler elevation, sectional area, rotate speed, step frequency, pipe length, signal junction depth and so on. Experimental studies of these factors were carried out respectively, the regularity of range influencing factors was found. The inlet press and sectional area were direct proportion to the range of the sprinkler, rotate speed and step frequency were inverse proportion to the range of the sprinkler, pipe length and signal junction depth were lessinfluence the range of the sprinkler. Orthogonal array of five factors and four levels were selected to carry out the experiment. The dates were analyzed by the method of synthesis point rating. The graduations of range influencing factors were achieved after the orthogonal experiments. They were inlet press, sprinkler elevation, sectional area, signal junction depth, pipe length in sequence. The results showed that compared with active static slice method, varible frequency speed control could save energy by 27%.
