Abstract

La invención se refiere a un dispositivo empleado para medir la carga de gas en un líquido, que incluye un aparato de medición, que consiste, esencialmente, en una bomba de pistones. Este aparato permite que se someta una cantidad de muestra del líquido a una presión negativa en una cámara cilíndrica de medición, siendo succionada hacia el exterior y determinada, de esta manera, la cantidad de gas disuelto, según la ley de los gases, variando las condiciones de presión y / o temperatura en la cámara cilíndrica. Según la invención, el aparato de medición es particularmente compacto y está dotado de un motor de control que actúa como activador de la bomba de pistones, lo que permite no sólo la generación de presión negativa en la cámara de medición, sino también la recirculación, desde la cámara cilíndrica de medición, de la muestra sometida a la medición, después del procedimiento de medición. En una realización particularmente preferida, el aparato de medición incluye un generador ultrasónico que expone a ultrasonidos la muestra que ha de medirse, lo cual permite reducir sustancialmente el tiempo de succión hacia fuera requerido para la expulsión del gas.
