| Abstract: | This paper describes the design and experimental evaluation of a novel radiometric instrumentation system that has been recently developed for the measurement of velocity, concentration and mass flow rate of solids in a pneumatic pipeline. The system employs a novel multi-beam, micro-sensing field interrogating the entire pipe cross-section to accommodate the irregularity of the solids velocity profile and inhomogeneity of the solids distribution within the pipeline. Experimental results obtained on a pneumatic conveyer circulating ilmenite powder demonstrate that the system is capable of detecting various velocity profiles and solids distributions across the pipe section and providing an absolute mass flow rate of solids within a good agreement to the reference reading from load cells. |
