Abstract
A liquid sprayer has a tank for storing liquid, a boom supporting spraying nozzles, and a pump and liquid control system for supplying liquid under pressure to the spraying nozzle in a manner that maintains substantially uniform liquid dispensing density independent of variations in the ground speed of the sprayer. A ground speed sensor, a liquid pressure sensor, and a liquid flow meter sends signals to a controller to regulate a valve that controls the rate of flow of liquid to the spraying nozzles.
