ABSTRACT:
A very simple system to automatically control the flow of irrigation water. The stem of a water shutoff valve is controlled by a balance beam having two arms extending perpendicular to the axis of rotation of the valve stem. The angle between the two arms is about 135 degrees. At the end of the second arm is a water bucket. At the end of the first arm is a counter weight. When the first arm is horizontal, the water bucket is elevated and the valve is open. The water bucket collects a small portion of the irrigation water flow. When the bucket is substantially full, the second arm moves to a horizontal position, the counterweight is elevated and the valve is closed.
