Irrigreen requires constant pressure between 40 and 80 PSI. Too little pressure will reduce throw distance, and too much can damage your sprinkler's pressure sensor.

To measure your pressure, attach a pressure gauge to an outdoor hose bib or the point of connection on your mainline. Turn the water on fully and record the reading. If the gauge is fluctuating, you have dynamic pressure and may need a pressure regulating valve (PRV) before installing.
