Abstract

SE PRESENTA UN METODO Y UN APARATO CON EL QUE SE PUEDEN REDUCIR LOS ERRORES CAUSADOS POR LA PROPAGACION DE MODOS ACUSTICOS DE ALTO NIVEL EN UNA MEDICION ULTRASONICA DEL CAUDAL. SE TRANSMITEN PAQUETES DE ONDAS ACUSTICAS ENTRE DOS TRANSDUCTORES (1, 2) QUE HAY COLOCADOS EN UN CONDUCTO (3). UN DISPOSITIVO DE CONTROL (4) UTILIZA E IMPLEMENTA UNA TECNICA DE TRANSMISION CIRCULAR EN QUE UNO DE CADA CUATRO PAQUETES DE ONDAS SE INVIERTE RESPECTO A LOS PAQUETES PRECEDENTES PARA ANULAR LOS EFECTOS DE PROPAGACION DE LOS MODOS DE ALTO NIVEL EN EL CONDUCTO (3). ESTE PERMITE QUE LOS TRANSDUCTORES (1, 2) DETECTEN LA RECEPCION DE LOS PAQUETES DE ONDAS CON UNA MAYOR PRECISION (1, 2) CON LO QUE SE CONSIGUE UNA MAYOR PRECISION AL MEDIR LA VELOCIDAD DEL CAUDAL.
