Abstract
A sprayer control system and method for using same includes a pump for directing a mixture of chemical and fluid carrier to a flow control valve. The flow control valve includes an intake port, a bypass port, and a regulated outlet port. A valve member is rotatable to direct fluid from the intake port either to the bypass port or the regulated output port. Fluid from the bypass port is sent through a bypass line back to the intake opening of the fluid pump. Various chemical tanks are connected to the bypass line for injecting metered amounts of chemical into the bypass line.
