Method and device for measuring the density of a liquid

摘要

The measuring device (10) consists of a measuring vessel (11) which is sealed in a pressure tight fashion by a cover (21) in which subatmospheric pressure prevails, and in which there are provided two cylinders (15, 25) which are situated concentrically with one another, are open at one end and form communicating containers. In this arrangement, the inner cylinder (15), which is open at the top, guides the lift vessel (32) of an areometer (hydrometer) (31) past which the entire liquid phase of the medium (17) is guided. <IMAGE>
