Abstract
INDICADOR DE NIVEL (12), ESPECIALMENTE PARA DEPOSITOS DE COMBUSTIBLE (10) DE VEHICULOS AUTOMOVILES, EN EL QUE SE PROVOCAN ONDAS DE FLEXION (17) EN UN PROPAGADOR SONICO (11) POR MEDIO DE UN EMISOR (13). PARA LA DETERMINACION DE LOS VALORES DE MEDIDA SE UTILIZARA LA REACCION SOBRE LAS MAGNITUDES DEL CAMPO ACUSTICO, FUNCION DEL NIVEL (H), EN EL PROPAGADOR SONICO (11) EN EL LUGAR EN QUE SE ENCUENTRA EL EMISOR (13) O EN SUS ALREDEDORES (LIMITANCIA SONICA). DE ESTE MODO SE EVALUARA LA VARIACION DE LA IMPEDANCIA TRANSVERSAL. SE OBTIENE UNA TRAYECTORA DE MEDIDA LINEAL, QUE PUEDE ASOCIARSE UNIVOCAMENTE CON UN NIVEL (H) DENTRO DE UN SEMIANGULO DE LA VARIACION DEL ANGULO DE FASE.
