摘要：
The present inventors have recognized that a pressure gradient or differentialin aproduct distribution line for conveying granular particulate material, such asseed orfertilizer, in an air flow to an agricultural field consistently decreases asair speed(velocity) in the product distribution line decreases until a critical airspeed is reached.Below the critical air speed, the particulate material may become susceptibleto fallingout of the air flow and potentially causing a blockage in the system.Accordingly, acontrol system can retrieve from a data structure a predetermined air flowsettingindicating an optimum operating velocity above the critical air speed yetbelow amaximum air speed associated with inefficient operation. In one aspect, thepredetermined air flow setting can be retrieved based on the type ofparticulate materialand/or rate at which the particulate material is metered.
