摘要：
A method and system has been developed to individually control the flow of liquid products from any nozzle within a plurality of nozzles using pulse width modulated solenoid actuated valves. The method and system simultaneously controls multiple flow and shutoff related inputs including but not limited to turn radius, nozzle overlap, swath reduction, nozzle spacing, fence row rates, wheel track rates, etc. The method and system will also simultaneously accept one or more external inputs from commercially available application rate control devices where other rate and shutoff inputs may be used, for example, variable rates per boom section based on GIS maps or multiple in-field sensors along the boom. The method and system further incorporates the artificial manipulation of commercial rate controller inputs and outputs to facilitate these individual nozzle control features and benefits without compromising the overall system flow control performed by the commercial rate controller.
