Abstract

PROCEDIMIENTO Y APARATO DE DETECCION DE IMPUREZAS EN LIQUIDOS. UN DISPOSITIVO ULTRASONICO DOPPLER DIRIGE UNA RADIACION, A TRAVES DE UN TRANSDUCTOR (12), HACIA LA CIRCULACION DE LIQUIDO (14); EL MISMO TRANSDUCTOR (12) RECOGE LA RADIACION REFLEJADA POR EL FLUIDO, PROPORCIONANDO UNA SEÑAL A UN MEDITOR DE CAUDAL DOPPLER (18), Y ESTE, A SU VEZ, PRODUCE UNA SEÑAL DE SALIDA, AMPLIFICADA (20), EN UN DISPOSITIVO ANALIZADOR. ESTE DETERMINA, A TRAVES DE UN ANALIZADOR DE ESPECTRO (22) Y UN PROMEDIADOR DE ESPECTRO (26), UNA INDICACION DE LA PRESENCIA DE IMPUREZAS EN EL FLUIDO.
