Abstract

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.
