Zusammenfassung:A system for metering liquids at very low flows for use with agricultural sprayers is provided. The system may utilize two electronically controlled solenoid valves in series with a storage chamber in between. The flow may be a function of the PWM control of each of the valves, the phase relationship between the control signals, the storage chamber in between, the pressure difference across the metering device, and the fluid being metered.
