5.0 FLOW CHARACTERISTICS
Each Ultimatic ER nozzle has a pressure rating on the face of the baffle which can be seen by looking at the front end of the nozzle.
Make sure that the pump system that is being used is capable of the flows and pressures of the selected Ultimatic ER Model.
Automatic nozzles operate by sensing the pressure at the nozzle inlet and adjusting the discharge opening to maintain a constant
pressure throughout the flow range of the nozzle. For example, when the pressure at the inlet increases, the exit area is automatically
increased until the inlet pressure returns to the nominal pressure of the nozzle.

5.1 REACH AND TRAJECTORY
These trajectories, reach and reaction numbers are provided for reference. All data based on 30 degree nozzle discharge angle, in
straight stream setting. Actual trajectories, reach and reactions may vary with wind conditions, fluid type, fluid/water ratio, fluid
temperature, pressure and flow at the nozzle. It is the operator’s responsibility to determine that the system provides adequate reach for
the intended purpose.

nozzle controls
pattern control
ER Bubble Cup nozzles have full pattern control from Off through low flow patterns and high flow patterns. The nozzle can be operated manually by turning the SHAPER clockwise (as seen from the operating position behind the nozzle) to move to the straight stream position. The pattern can be adjusted either by operating the electric actuator or by manually rotating the shaper.
