Recalibration Methodology To Compensate For Changing Fluid Properties In An Individual Nozzle Direct Injection Systems, Joe D. Luck, S. A. Shearer, B. D. Luck, M. P. Sama

Biological Systems Engineering: Papers and Publications

Limited advancement of direct injection pesticide application systems has been made in recent years, which has hindered further commercialization of this technology. One approach to solving the lag and mixing issues typically associated with injection-based systems is high-pressure individual nozzle injection. However, accurate monitoring of the chemical concentrate flow rate can pose a challenge due to the high pressure, low flow, and changing viscosities of the fluid. A methodology was developed for recalibrating high-pressure chemical concentrate injectors to compensate for fluid property variations and evaluate the performance of this technique for operating injectors in an open-loop configuration. Specific objectives were …
