Abstract

"MéTODO DE MEDIçãO DO NìVEL DE PREENCHIMENTO DE UM REATOR". Em um método de medição do nível de preenchimento de um reator em processos de polimerização operados continuamente, que usam medidas da respectiva interface de fases no reator por meio de radiação ionizante, pelo menos uma unidade de medição compreendendo uma fonte de radiação que emite radiação ionizante e um correspondente detector são trazidos até a interface de fases do reator e é flexivelmente instalado lá, com o nível de preenchimento do reator sendo medido pela determinação da interface de fases por meio da medida da dispersão radioativa refletida.
