Abstract

SE PRESENTA UN MEDIDOR ELECTRONICO DEL CAUDAL DE FLUIDOS (50) QUE INCLUYE UN DISPOSITIVO DIGITAL DE LSI (1) Y UN DISPOSITIVO ANALOGICO DE LSI (2). EL DISPOSITIVO DIGITAL (1) ACCIONA UN PAR DE TRANSDUCTORES ACUSTICOS (5, 6) PARA TRANSMITIR ONDAS ACUSTICAS DENTRO DE UN FLUIDO, CUYO CAUDAL SE VA A MEDIR. LAS ONDAS ACUSTICAS SON RECIBIDAS EN EL DISPOSITIVO ANALOGICO (2), DETERMINANDOSE EL MOMENTO DE LLEGADA MEDIANTE UNA DETECCION DE ENVOLVENTE ASOCIADA A LA FASE DE LA SEÑAL RECIBIDA. LA RECEPCION DE UNA SEÑAL DETIENE UN CONTADOR (23) QUE HAY COLOCADO DENTRO DEL DISPOSITIVO DIGITAL (1), EN DONDE EL VALOR DEL CONTADOR (23) REPRESENTA EL TIEMPO DE VUELO DE LAS SEÑALES ACUSTICAS DENTRO DEL FLUIDO. LOS DATOS SOBRE EL CAUDAL DEL FLUIDO SE PUEDEN ALMACENAR EN UNA EEPROM (4) DE LA QUE SE PUEDEN LEER LOS DATOS DEL MEDIDOR UTILIZANDO UNA PANTALLA DE CRISTAL LIQUIDO (7) O A TRAVES DE UN PUERTO DE INTERFAZ (3) A UN DISPOSITIVO EXTERNO.
