ABSTRACT:
A fluid control system for controlling one or more branches of a fluid delivery system, which can be manually controlled or, under general operating conditions, automatically controlled by ambient moisture conditions. When applied to sprinkler and irrigation systems, for example, the system will include a ground moisture sensor which, with associated means, can modify or adjust the preset watering times in accordance with soil needs as sensed by the sensor structure. The programmable timer is used for respective watering stations; the timers can be separately set to desired average watering time needed for particular stations. Sequencing functions and apparatus are also provided.
