To enlarge the scope of working pressure for complete fluidic sprinkler, turning angle was applied in the effuser, which can increase intrinsic driving moment. The important geometrical parameters for the turning angle effuser included angle and arm of force. The equations of total driving moment and stepping angle were deduced. Experiments were carried out on seven types of effusers with different turning angles or arms of force. The results showed that testing value agrees well with the theoretical analyzing. Working pressure, with a small infection on stepping angle, positively influences wetted diameter, uniformity coefficient and stepping frequency. Turning angle positively influences stepping angle and uniformity coefficient, and negatively influenced stepping frequency. Turning arm of force positively influenced stepping angle, negatively influenced wetted diameter.
