Systems obtaining real-time mass flow data were developed to support cotton gin automation. The experimental systems used the attenuation of optical and ultrasonic signals, inertia, and air pressure differences caused by changes in potential energy. A conveyor belt standard indicated real-time accuracy while a truck scale standard verified accuracy integrated over time. Conveying air velocity pressure and vertical pipe air pressure differential most accurately reflected mass flow. Their estimate of mass flow rate in real time was within 10% of the belt scale. Both systems are inexpensive to make and easy to add to an existing cotton gin.
