Abstract
LA PRESENTE INVENCION SE REFIERE A UN CONTADOR DE FLUIDO CON REMOLINOS (1) QUE COMPRENDE UNA CONDUCCION (2) DE DIAMETRO INTERIOR MAXIMO D EN LA QUE CIRCULA EL FLUIDO Y ESTA FORMADA POR UN PERFIL FORMADO SUCESIVAMENTE DE CORRIENTE ARRIBA A CORRIENTE ABAJO POR UNA PRIMERA PARTE (4) QUE REDUCE PROGRESIVAMENTE EL DIAMETRO INTERIOR DE DICHA COPNDUCCION A UN VALOR D1 Y QUE TIENE UNA PARED INTERIOR (4AM 4B, 4C, 4D) QUE FORMA CON LA DIRECCION GENERAL DE CIRCULACION DEL FLUIDO UN ANGULO COPNMTINUAMENTE VARIABLE, POR UNA SEGUNDA PARTE (6) DE DIAMETRO CONSTANTE D1 EN LA QUE ESTA DISPUESTO AL MENOS UN OBSTACULO (8) APTO PARA GENERAR REMOLINOS DE FLUIDO OSCILANTES Y POR UNA TERCERA PARTE (20) DE CONDUCCION QUE DEVUELVE EL DIAMETRO INTERIOR DE DICHA CONDUCCION (2) A SU VALOR INICIAL (D) Y QUE ES APTA PARA PROVOCAR EL DESPEQGUE DE LA CAPA LIMITE DE CIRCULACION DEL FLUIDO A LA ALTURA DE UN EXTREMO LLAMADO CORRIENTE ABAJO (6A) DE LA SEGUNDA PARTE (6) DE CONDUCCION, ASI COMO MEDIOS (10, 12, 14, 16, 18, 200,221) PARA DETECTAR LA SEÑAL QUE CORRESPONDE A LAS OSCILACIONES DE LOS REMOLINOS Y PARA REDUCIR EL VOLUMEN O EL CAUDAL DE FLUIDO.
