Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA A DETERMINAçãO DO NìVEL DE ENCHIMENTO DE RECIPIENTES"<D>. Para a determinação do nível de enchimento em recipientes são geradas vibrações mecânicas na parede de um recipiente (30) e o percurso destas vibrações é analisado. A parede do recipiente onde a vibração é gerada é tocada em distâncias diferentes de acordo com o nível de enchimento. Em seguida, o padrão das vibrações é avaliado quanto à distância na qual o lado interno da parede do recipiente (30) é tocado. Deste modo é possível determinar o tempo de decaimento, a freq³ência, a intensidade e/ou o integral de tempo da intensidade ou o ponto da intensidade máximo das vibrações mecânicas na parede do recipiente.
