Irrigation gate system
First Claim
1. An irrigation gate system for controlling the flow of water in a water canal comprising:
- b. a rotateable gate positioned in the water canal, the gate for moving between a closed position preventing water upstream of the gate from flowing past the gate and a plurality of open positions to allow variable amounts of water to flow past the gate;
c. a gate actuator for rotating the gate between positions;
d. a controller in communication with the gate actuator for providing signals to direct the gate actuator to rotate the gate between positions;
e. a sensor in communication with the controller for providing the sensor'"'"'s readings to the controller; and
f. the controller calculating the difference between the readings provided by the sensor and a pre-programmed condition stored in the memory of the controller and providing signals to the gate actuator based on the difference between the readings and the pre-programmed condition.

Abstract
An irrigation gate system installed in a channel (such as a ditch or canal) for controlling the flow of water through the channel maintaining a desired level of water upstream from the irrigation gate system or for controlling water flow downstream from the irrigation gate system. The irrigation gate system includes a gate which is maintained in a closed position for preventing water flow past the gate or alternatively, in one of a plurality of open positions for allowing desired amounts of water in the channel to flow past the gate. The gate is vertically hingedly connected to a pipe shaft supported by a frame installed in the channel. A gate actuator moves the gate between its various positions upon receiving signals from an electronic programmable controller which in turn may receive signals from a variety of sources.
