Abstract (en)
[origin: FR2784975A1] Each conveying section has a pressure or speed flow meter (10) monitoring the of the air inside or outside the pneumatic conveyor (5). The flow meter delivers one or more control signals (10a). A regulator (11) and a frequency changer (13) regulate the rotational speed of the motors (M) of each fan (6). The regulator receives the input signal from the flow meter as well as a signal (12a) delivered by a programmable robot (12).
