Abstract

DISPOSITIVO DE MEDIDA DOPPLER PARA LA MEDICION DE LA VELOCIDAD DE FLUJO DE UN FLUIDO (11) QUE ARRASTRA PARTICULAS (12) QUE REFLEJAN LAS ONDAS ULTRASONICAS. TAL DISPOSITIVO CONTIENE LAS SIGUIENTES PARTES: UN CONVERTIDOR DE ULTRASONIDOS (14) PARA IRRADIAR EL FLUIDO CON IMPULSOS DE ONDAS ULTRASONICAS EN REACCION A LOS CORRESPONDIENTES IMPULSOS DE EMISION QUE SON DIRIGIDOS A EL CON UNA FRECUENCIA DE REPETICION DE IMPULSO PREDETERMINADA PARA RECIBIR LAS ONDAS ECO REFLEJADAS POR LAS PARTICULAS DE FLUIDO, Y PARA LA EMISION DE LAS CORRESPONDIENTES SEÑALES ECO; UN EMISOR (15) CONECTADO CON EL CONVERTIDOR DE ULTRASONIDOS (14) PARA LA PRODUCCION DE IMPULSOS DE EMISION CON LOS QUE SE ACTIVA EL CONVERTIDOR DE ULTRASONIDOS PARA LA EMISION DE IMPULSOS DE ONDAS ULTRASONICAS; UN RECEPTOR (16) CONECTADO CON EL CONVERTIDOR DE ULTRASONIDOS (14) PARA LA RECEPCION Y PROCESAMIENTO DE SEÑALES ECO, QUE, POR LO MENOS, CORRESPONDEN A DOS GRUPOS DE ONDAS ECO QUE SON REFLEJADAS POR LAS PARTICULAS DE FLUIDO EN REACCION A UNA PRIMERA Y UNA SEGUNDA EMISION DE IMPULSOS DE ONDAS, DONDE LAS BANDAS DE FRECUENCIA DE LAS SEÑALES ECO VECINAS PERO SEPARADAS ENTRE SI SON PROCESADAS CADA UNA EN UNA SENDA DE PROCESAMIENTO DE SEÑALES SEPARADA (21, 22); UNA UNIDAD DE ANALISIS (18) CONECTADA CON LA SALIDA DEL RECEPTOR (16) MEDIANTE LA CUAL SE OBTIENE, A PARTIR LA INFORMACION DOPPLER CONSEGUIDA CON EL RECEPTOR, UNA SEÑAL DE SALIDA QUE CORRESPONDE A LA VELOCIDAD DE FLUJO. PARA AUMENTAR LA SENSIBILIDAD DEL DISPOSITIVO, EL EMISOR (15) ESTA CONSISTITUIDO DE TAL FORMA QUE EL ESPECTRO DE FRECUENCIAS DE LA SUCESION PERIODICA DE IMPULSOS DE EMISION CONSTA DE DOS BANDAS DE FRECUENCIA VECINAS, PERO SEPARADAS ENTRE SI.
