1. A localized product injection interface comprising:
one or more interface bodies configured for coupling with a boom tube, the boom tube coupled with one or more upstream pumps configured to pressurize a carrier fluid and an injection product, the one or more interface bodies configured to mix the carrier fluid and the injection product to form an agricultural product and provide the agricultural product for spray application, each interface body of the one or more interface bodies houses:
a carrier fluid fitting configured to couple with a carrier fluid passage of the boom tube and receive the carrier fluid pressurized with the one or more upstream pumps;
an injection product fitting configured to couple with an injection product passage of the boom tube and receive the injection product pressurized with the one or more upstream pumps;
an injection control valve, the injection product fitting extending to the injection control valve, the injection control valve is configured to control an injection flow rate of the injection product;
a mixing chamber, the carrier fluid fitting and injection control valve extending to the mixing chamber, the mixing chamber includes a static mixer configured to mix the injection product at the injection flow rate with the carrier fluid from the carrier fluid fitting in each interface body and provide the agricultural product; and
at least one flow measuring sensor proximate to the injection control valve;
wherein the at least one flow measuring sensor measures at least one of flow rate or pressure differential of the injection product;
wherein the injection control valve is configured to meter a quantity of the injection product to the mixing chamber according to the measured at least one of flow rate or pressure differential of the injection product; and
a plurality of nozzle assemblies, each nozzle assembly engaged with at least one of the one or more interface bodies;
wherein each nozzle assembly of the plurality of nozzle assemblies is in direct communication with the mixing chamber housed in at least one of the one or more interface bodies, and each nozzle assembly is configured to spray the agricultural product pressurized with the one or more upstream pumps;
wherein the agricultural product sprayed from each nozzle assembly includes a concentration of injection product specific to each nozzle assembly.
