Abstract

PROCEDIMIENTO PARA EL ANALISIS CONTINUO DE LA COMPOSICION DE GASES MEDIANTE UNA CABEZA DE MEDICION PARA DETERMINAR LA VELOCIDAD DEL FLUJO, Y EQUIPO DE ANALISIS, QUE SE COLOCA A UNA DISTANCIA, SEPARADO DE LA CABEZA DE MEDICION, Y SE CONECTA A LA MISMA POR UNA LINEA DE MUESTRAS, ALIMENTANDOSE UN GAS DE CALIBRACION A LA LINEA DE MUESTRAS EN LA CABEZA DE MEDICICION, MEDIANTE LA CUAL SE DETERMINA EL TIEMPO DE TRANSITO DE LOS GASES, Y MEDIANTE ESTE TIEMPO DE TRANSITO SE INTRODUCE UNA VARIACION DE FASE DURANTE LA DETERMINACION DE LA CONEXION ENTRE LA VELOCIDAD DEL FLUJO Y LA COMPOSICION. DE CONFORMIDAD CON LA INVENCION, SE ALIMENTA UNA SERIE DE IMPULSOS DE GAS DE CALIBRACION DESDE EL EQUIPO, Y SE DETERMINA EN SEGUIDA EL PROMEDIO DEL TIEMPO DE TRANSITO DE LOS GASES EN LAS CONDICIONES QUE PREVALECEN LOCALMENTE EN ESE MOMENTO, PARA LA DETERMINACION ESENCIALMENTE CONTINUA DE LA CONEXION ENTRE LA VELOCIDAD DEL FLUJO Y LA COMPOSICION. DISPOSITIVO PARA REALIZAR EL PROCEDIMIENTO QUE COMPRENDE LA CABEZA (5) DE MEDICION Y EL EQUIPO (1) DE ANALISIS PARA DETERMINAR LA COMPOSICION DE LOS GASES, PROVISTO CON UNA FUENTE (7) DEL GAS DE CALIBRACION EN EL EQUIPO DE ANALISIS (1), UNA LINEA (9) DEL GAS DE CALIBRACION, CONECTADA EN (11) A LA LINEA DE MUESTRAS, A UNA DISTANCIA CORTA DE LA ABERTURA DE SUCCION DE LA MISMA, CON LA CABEZA (5) DE MEDICION, MEDIO PARA MANTENER EL GAS DE CALIBRACION BAJO PRESION, MEDIO PARA ABRIR PERIODICAMENTE UNA VALVULA EN LA LINEA DEL GAS DE CALIBRACION, Y MEDIO (12) PARA DETERMINAR EL TIEMPO DE TRANSITO DE LOS IMPULSOS DEL GAS DE CALIBRACION A TRAVES DE LA LINEA DE MUESTRAS.
