Abstract

resumo patente de invenção: "medição de superfície intermitente". a presente invenção refere-se a um método para determinar um nível de preenchimento de um produto contido em um tanque, sendo que o método compreende as etapas de: a) transmitir um sinal de sondagem eletromagnético em direção a uma área alvo de uma superfície do dito produto; b) receber um sinal de sondagem refletido que é uma reflexão do sinal de sondagem eletromagnético na dita superfície; c) determinar um valor de parâmetro indicativo de uma amplitude do sinal de sondagem refletido; se o valor de parâmetro for indicativo de uma amplitude maior que um valor limiar predeterminado: d) transmitir um sinal de medição eletromagnético em direção à dita área alvo da superfície; e) receber um sinal de retorno que é uma reflexão do sinal de medição eletromagnético na superfície; e f) determinar o nível de preenchimento com base em uma relação de tempo entre o sinal de medição eletromagnético e o sinal de retorno.
