Abstract
A system for transporting measured amounts of bulk material from a first site to a remote site generally comprising means for holding a mass of material to be transported to the receptacle; means for transporting the material from the holding means to the receptacle; means for injecting a gas under pressure into the transporting means for pneumatically conveying material received from the holding means to the receptacle, operable in continuous and intermittent modes; means for sensing the weight of the receptacle; and a programmable logic controller operatively connected to the sensing means and the injecting means, operable responsive to a weight of the receptacle up to a first weight for operating the injection means in the continuous mode, a weight of the receptacle between the first weight and up to a second weight greater than the first weight for operating the injection means in the intermittent mode and to the second weight for discontinuing the injection means.
