(4745) Range (of a sprinkler or diffuser)
The maximum distance, measured under normal operation, between the vertical axis of a sprinkler and the outer edge of the wetted pattern. Some authorities define that outer edge as the distance where the sprinkler intensity falls below 0.25 mm/hr. (for a sprinkler with discharge greater than 75 l/hr.) and below 0.13 mm/hr. (for a sprinkler with discharge less than or equal to 75 l/hr).
