1. A pneumatic transport system of granular material, configured to convey granular material from one or more storage containers to one or more processing machines, the system comprising:
at least one loading device of the granular material, to be associated to a processing machine to feed the processing machine with granular material, said loading device being provided with a collection tank of the granular material; at least one conveying duct of granular material which fluidically connects the collection tank to at least one storage container of granular material to transfer the granular material from the container to the tank; and means for generating flow of granular material inside the conveying duct a flow from the container to the tank of the loading device; at least one sensor for each loading device to detect vibrations induced by the material which is being loaded inside the loading device, said at least one sensor being positioned next to or in correspondence of the loading device and generating time signals of the vibrations which can be correlated to mass of the granular material being progressively loaded in the collection tank, or to a volume of the collection tank progressively filled by said granular material. |
