Abstract
MEDIDOR DE GáS A invenção diz respeito a um medidor de gás consistindo de um tubo de medição ultrassónica, com o eixo longitudinal incluindo uma parte interna em que ocorre o fluxo de gás, ao menos, dois transdutores ultrassónicos distribuídos ao longo do eixo longitudinal. A invenção é caracterizada pelo fato do referido medidor compreender, entre cada transdutor e a parte interna do tubo de medição, uma parte de maior largura, relativamente às dimensões da superfície ativa do referido transdutor, o referido medidor compreendendo no mínimo um elemento localizado em uma das referidas partes mais largas e estendendo-se sobre toda a sua parte interna, de modo a formar uma tela de filtração com relação às partículas de poeira transportadas pelo gás, sendo o referido elemento atravessado pelas ondas ultrassónicas emitidas pelos transdutores por, ao menos, parte de sua largura, que é maior do que as dimensões das referidas superfícies ativas dos transdutores.
