PURPOSE:To realize higher reliability, by calculating existing informations of assumed correcting factors by comparing total sum of flow of a powdery granule in a branched tube and decrement of a storage container and by obtaining an actual flow rate of the powdery granule basing upon said informations, carrier gas informations and pressure informations, etc. CONSTITUTION:Flow meters 6a-6c and manometers 8a-8c installed in gas-flow sections 3a1-3c1, manometers 9a-9c and a computer 10 in double-flow sections 3a2-3c2 respectively are connected through flow rate transmitters 7a-7c, pressure transmitters 11a-11c, 12a-12c respectively. The computer 10 calculates the existing informations of assumed correcting factors by the total sum of flow rate of the powdery granule in the branched tubes 3a-3c and decrement of the storage container 1 and from the existing informations of correcting factors thus calculated, flow rate informations of carrier gas 4 and pressure information in process of transportation of the powdery granule, the existing flows of the powderous material in the individual branched tubes 3a-3c are obtained. |
