Resumo

Due to the penetrating properties of gamma radiation, radiotracers are exceptionally better over other tracers due to their high detection sensitivity. Usually, a small volume is injected, and after the distance necessary for the radiotracer to be completely mixed with the main fluid, scintillator detectors are installed to record the radioactive cloud movement. When measuring flow in pipelines using the time transient method, it is usual to consider the fluid flow velocity constant all over the pipeline, but it is essential that the scintillator detectors are positioned correctly in order to accurately measure the transient time between two points. The results presented were measured in the aqueous flow pipeline constructed with 1" internal diameter stainless steel tubes and using 82Br as a radiotracer. The results prove that the accuracy of the final result depends on the correct position of the scintillator detectors
