Abstract
UN APARATO Y UN METODO PARA DETECTAR UNA INTERFASE LIQUIDO/GAS QUE FLUYE EN UN TUBO TRANSPARENTE (12), COMPRENDE DIRIGIR LUZ RADIALMENTE A TRAVES DEL TUBO TRANSPARENTE DE MANERA PERPENDICULAR A SU EJE LONGITUDINAL, PARA QUE LA LUZ DIRIGIDA RADIALMENTE PASE A TRAVES DEL TUBO, CUANDO ESTA LLENO CON LIQUIDO ESO LA LUZ SE EXTENDERA SUSTANCIALMENTE DENTRO DE UNA ZONA PREDETERMINADA (14) Y CUANDO ESTE RELLENO CON GAS SE EXTENDERA MAS ALLA DE LA ZONA PREDETERMINADA (14). LA LUZ SE RECIBE EN UNA POSICION (14) DIAMETRALMENTE OPUESTA A UNA POSICION (10) DESDE LA QUE SE DIRIGE LA LUZ RECIBIENDO SOLO LA LUZ QUE PASA A TRAVES DEL TUBO Y SE PROLONGA MAS ALLA DE UNA ZONA PREDETERMINADA. UNA SEÑAL DE SALIDA REPRESENTATIVA DE LIQUIDO O GAS EN EL TUBO SE PRODUCE EN RESPUESTA A LA CANTIDAD DE LUZ RECIBIDA. UN SEGUNDO RECEPTOR DE LUZ (15) DISPUESTO FUERA DE LA ZONA SE USA PARA DETERMINAR LA DIRECCION DEL FLUJO.
