Resumo: The proposal of this research was to develop a methodology using gamma radiation and cross-correlation techniques to measure the speed of ore pellets in a hydrotansport duct. An experimental unit was designed and built to be used in a two-phase flows transport simulation It was used to measure the velocity of the solid pellets. The flowmeter system consists in two independent systems, each one composed by a NaI (1x1”) scintillators detector- 241Am gamma source, installed outside the tube, both systems were located in the same vertical plane and separated by 18.0 cm. As pellets, were produced a variety of specimens with different compositions in order to verify the methodology. Using this flowmeter was possible to calculate the solid phase velocity.
