Abstract

MÉTODO PARA DETERMINAR TEMPO DE ATRASO DE TRANSDUTOR E SEPARAÇÃO DE TRANSDUTOR EM MEDIDORES DE FLUXO ULTRA-SÔNICOS, E, MEDIDOR ULTRA-SÔNICO. Método e sistemas relacionados para determinar tempo de atraso de transdutor e separação de transdutor em medidores de fluxo ultrasônicos. Pelo menos algumas das concretizações ilustrativas são um método incluindo medir um tempo de atraso para um primeiro par de transdutores, medir um tempo medido total para sinais ultra-sônicos transmitidos entre um segundo par de transdutores em um medidor ultra-sônico no qual ambos o primeiro e segundo pares de transdutores estão instalados, calcular em parâmetro associado com o segundo par de transdutores usando o tempo de atraso do primeiro par de transdutores e o tempo medido total patra dito segundo par de trandutores.
