A sprinkler system timer is an electrical device that is used to set an irrigation sprinkler system to come on automatically at a certain time. Irrigation timers first appeared in the early 1960s to control large-radius lawn sprinklers, which at the time usually contained their own electrically operated valve (most golf-course sprinklers still use this type of actuation).
Rain Clox was the trade name given to a series of electromechanical irrigation controllers produced by the Rain Bird Corporation from 1962 to the late 2000s (decade), and were largely responsible for giving rise to the widespread use of automatic irrigation. The first model was the ME11AB, capable of running 11 stations on two schedules.
The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [3] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.
Most automatic irrigation valves are diaphragm valves in which the water above the diaphragm must be discharged for the valve to open. In a hydraulic system, the controller and valves are connected via small plastic tubes approximately 4 mm (¼ in) in diameter. The controller opens the tube connected to the valve, allowing that valve to open.
It is used in conjunction with irrigation sprinklers to form an automated or non-automated sprinkler system, capable of administering precise amounts of water, at a regular basis. A water flow timer using a ball valve contains an electric motor with gears to stop or start the water flow by turning a perforated ball within the water flow line.
In the 1950s, Stout-Wyss Irrigation System, a firm based in Portland, Oregon, developed a rolling pipe type irrigation system for farms that has become the most popular type for farmers irrigating large fields. With this system, large wheels attached to the large pipes with sprinkler heads move slowly across the field. [4]
