In recent years, the agricultural industry has introduced new low-volume formulations for pest control. This trend toward post-emergence, selective chemical application has established a need for research and development of direct injection systems capable of precisely metering fluids of diverse flow characteristics. Ag Systems, Inc., is involved in the development of a precision delivery system (CompumistT*) whose operations are partially dictated by fluid variations due to temperatures which may range from 40 to 110 degrees F. Phase I research established the feasibility of precision micrometering of modern agri-chemicals for temperature ranges and material properties pertinent to wide-ranging farming applications. Research results enable an intelligent software algorithm to accurately determine motor speed for specific chemical mixtures. Phase II work will integrate the precision, flow independent fluid metering technology into a comprehensive programmable, precision direct injection. monitoring and reporting system utilizing the smart pump concept. .Applications:Accurate metering and applying of agricultural chemicals can reduce chemical costs, chemical wastes and environmental degradation. National long range benefits include a balance of trade improvement through retention of domestic production and exploration of state-of-the-art farm machinery. Research dating back as far as 1980 indicates that the farming industry is consistently losing in excess of one billion dollars annually. Until the industry is provided with equipment that is accurate and reliable. these cost will continue to escalate.
