摘要:
A sprinkler which is controllable to provide water to an area to be sprinkled includes a sprinkler head to move between a first position and a second position. The sprinkler further includes a sprinkler head positioner to move the sprinkler head between the first and second positions, a sprinkler head position determiner to determine a current sprinkler head position between the first and second positions, a flow control valve to control flow of water from a water supply to the sprinkler head, a flow control valve positioner to establish a current control valve position for the flow control valve between an essentially fully closed control valve position and an essentially fully open control valve position, and a controller to receive a sprinkler head position signal from the sprinkler head position determiner and send a control valve control signal to the flow control valve positioner in response thereto.
