Abstract
A method of ascertaining the state of aggregation of a medium, whereby the flow of the medium is directed to a first of a series of two or more coaxially arranged nozzle means, further the initial pressure of said medium ahead of said series of nozzle means is compared with a further pressure, said pressure generated when following nozzles are flowed at directly through a respective preceding nozzle via a closed space arranged between two or more nozzles or following the final nozzle, and the correspondingly generated differential pressure is utilized as measurement value for indication of the state of aggregation and if necessary directly or indirectly for controlling the flow of said medium. The apparatus for carrying out the method comprises a casing means having an inlet port means and an outlet port means for a flowing medium, comprises further an inlet chamber means, an intermediate chamber means and a final chamber means arranged in succession, whereby said chamber means are separated from each other by wall means and every one of said wall means comprises a nozzle bore means arranged coaxially relative to each other, whereby further said inlet chamber means is in communicat…
