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 to potentially cause a blockage in the system.Accordingly, pressuresensors arranged in the product distribution line can be monitored foreffectivelycontrolling an air source producing the air flow. In one aspect, a diameter ofthe productdistribution line can increase between upstream and downstream locations formonitoringwith even greater sensitivity.
