Abstract
MEDIDOR ULTRASÈNICO DE FLUIDO COM RESISTêNCIA MELHORADA A ONDAS ULTRASÈNICAS PARASITAS. A invenção fornece um medidor de fluido (10) compreendendo transdutores (26, 28) ultrasónicos, mecanismos de atenuação para atenuação das ondas ultrasónicas parasitas de comprimento de onda <sym>, e constituídos pelo menos por uma passagem (36, 38, 40) aonde as referidas ondas se propagam ao longo de uma direção principal correspondendo a uma dimensão longitudinal <MU>a<MV> da referida passagem, a referida passagem apresentado uma dimensão transversal <MU>b<MV> perpendicular a <MU>a<MV> e muito menor do que o comprimento de onda <sym> das ondas parasitas no meio de propagação, a referida passagem compreendendo uma pluralidade de porções de passagens (46, 48) consecutivas, cada qual apresentando uma parte (46) com uma redução na seção de propagação transversal ao longo da dimensão <MU>b<MV> da passagem, a dimensão longitudinal de cada porção de passagem sendo substancialmente igual a (1/2) <sym>.
