Abstract

UN METODO Y APARATO PARA EL CONTROL NO INTRUSO DE UNA VALVULA DE RETENCION (20) QUE PROPORCIONAN UN ACELEROMETRO (24) Y UN TRANSDUCTOR ULTRASONICO (32) MONTADOS SOBRE EL CUERPO DE LA VALVULA DE RETENCION (28). EL ACELEROMETRO (24) Y EL TRANSDUCTOR (32) GENERAN SEÑALES CORRESPONDIENTES A LOS SONIDOS AUDIBLES QUE TIENEN LUGAR DENTRO DE LA VALVULA DE RETENCION (20) Y SEÑALES ULTRASONICAS REFLEJADAS TRANSMITIDAS A LA VALVULA DE RETENCION (20) POR EL TRANSDUCTOR (32). LAS SEÑALES SE GRABAN SIMULTANEAMENTE Y A CONTINUACION SE PROCESAN PARA OBTENER UNA REPRESENTACION VISUAL DE LAS CONDICIONES DENTRO DE LA VALVULA DE RETENCION (20).
