Abstract

Patente de Invenção: "MEDIçãO E CONTROLE DO FLUXO DE MATERIAIS QUE PODEM FLUIR". Um método de determinação de uma vazão de entrada (F~ inlet~) de um material que pode fluir, incluindo passar um fluxo de entrada de material que pode fluir através de uma câmara (20) que tem uma abertura de saída (100); medir uma primeira taxa de mudança de quantidade de material na câmara (20), quando o material estiver entrando na referida vazão de entrada; medir uma segunda taxa de mudança de quantidade de material na câmara (20), quando nenhum material estiver entrando na câmara (20); e calcular a vazão de entrada F~ inlet~ a partir das referidas primeira e segunda taxas, onde ambas as medições de taxa são conduzidas enquanto toda a abertura de saída (100) da câmara (20) é ocupada pelo material que pode fluir.
