The Ag-Nav Granular Flow Controller works in conjunction with the Isolair 4500 series Broadcaster system to provide even application of granules over the target areas. The Granular Flow Controller consists of one controller box, two granular dispensers and harness. Each granular dispenser has an impeller driven by a covered DC motor with a RPM encoder. -
Page 6: System Overview
System overview How the system works The AG-NAV Granular Flow Control system is designed to ensure a steady distribution of dry granular material by automatically adjusting the dispersal rate when the aircraft speed changes. The DC motors individually control the impeller RPM with feedback from the high precision Optical encoders. -
