Abstract

LA INVENCION SE REFIERE A UN METODO PARA DETERMINAR LAS CARACTERISTICAS DE UN FLUJO DE UN MEDIO EN UN CANAL MIDIENDO EL TIEMPO DE TRANSITO DE LAS ONDAS DE SONIDO QUE SON TRANSMITIDAS ENTRE UNO O MAS TRANSDUCTORES, Y DETERMINANDO LAS CARACTERISTICAS A PARTIR DE LOS TIEMPOS DE TRANSITO MEDIDOS. EN UNA CONFORMACION DEL METODO DE ACUERDO CON LA INVENCION, SE TRANSMITEN AL MENOS DOS ONDAS DE SONIDO, CUYO TIEMPO DE TRANSITO DEPENDEN DE LOS TORBELLINOS, A LO LARGO DE CAMINOS ACUSTICOS CON UNA SENSIBILIDAD DIFERENTE A LOS TORBELLINOS, Y SE DETERMINA UNA MEDICION DE LOS TORBELLINOS A PARTIR DE LOS TIEMPOS DE TRANSITO MEDIDOS. EN OTRA CONFORMACION, SE TRANSMITEN AL MENOS DOS ONDAS DE SONIDO CUYO TIEMPO DE TRANSITO DEPENDE DE LA SIMETRIA DEL PERFIL DE FLUJO, A LO LARGO DE CAMINOS ACUSTICOS CON UNA SENSIBILIDAD DIFERENTE A LA SIMETRIA, Y SE DETERMINA UNA MEDICION DE LA SIMETRIA A PARTIR DE LOS TIEMPOS DE TRANSITO MEDIDOS. ESTAS CONFORMACIONES PREFERIBLEMENTE SE COMBINAN. SI SE SITUAN FACTORES DE COMPENSACION JUNTO CON LOS VALORES OBTENIDOS, LAS VELOCIDADES INDIVIDUALES DE LAS ONDAS DE SONIDO PUEDEN UTILIZARSE PARA CALCULAR LA VELOCIDAD MEDIA DEL FLUJO DEL MEDIO. DESDE EL MOMENTO EN QUE SE PERMITEN POSIBLES PERTURBACIONES DEL PERFIL DE VELOCIDAD, LA EXACTITUD DE LAS VARIABLES CALCULADAS ES BUENA. LA INVENCION TAMBIEN SUMINISTRA UN DISPOSITIVO, POR MEDIO DEL CUAL EL METODO DE LA INVENCION PUEDE LLEVARSE A CABO.
