ABSTRACT
Five experimental mass flow measurement systems were tested against a weighing conveyor belt at the SW Cotton Ginning Research Lab. A certified truck scale verified accuracy integrated over time. Test systems measured the mass flow rate of pneumatically conveyed seed cotton with ultrasonic and optical signal attenuation, elbow inertial force, pressure difference in a vertical pipe and conveying air velocity pressure. Conveying air velocity pressure most accurately reflected mass flow in real time.
