Abstract
DISPOSITIVO PARA MEDIR LA VELOCIDAD DE UN FLUIDO QUE INCLUYE UN PAR DE TRANSDUCTORES ULTRASONICOS (T1,T2) SEPARADOS EN UNA CAMARA DE MEDICION. UN SISTEMA DE TRANSMISOR Y RECEPTOR ESTA CONTROLADO POR UN MICROPROCESADOR (100) QUE GENERA IMPULSOS QUE SE INVIERTEN PERIODICAMENTE Y ESTOS SON COMUTADOS POR CONMUTADORES (140,150) PARA POSIBILITAR UNA DIRECCION ALTERNA DE TRANSMISION. LA RECEPCION Y LA DETECCION DE SEÑALES ES EFECTUADA POR BLOQUES (152-168). EL CALCULO DEL TIEMPO ES DETERMINADO POR UN CONTADOR (109) Y LOS RESULTADOS SON UTILIZADOS PARA CALCULAR LA VELOCIDAD DEL FLUJO O EL VOLUMEN UTILIZANDO EL MICROPROCESADOR. SE EFECTUA UN AUMENTO DE LA VELOCIDAD EN LA ZONA DE MEDICION UTILIZANDO UN DISPOSITIVO VENTURI.
