Measuring device (ME3, ME4, ME5, ME6) for measuring the dynamic viscosity (·) and the density (p) as physical quantities of an essentially not or rather little compressible measuring medium (F), with a vessel (B) having a total volume (V 0 ), which is charged with a compressible medium (L) and into which a measuring medium (F, K) with a fraction volume (V X , V x(t) ) may be introduced, and with pressure means (DS, A) for measuring an initial pressure (P 1 , P A1 , P A2 ) and a modification internal pressure (P 2 , P 3 , P (1) ) in the vessel (B), in which modification means (KV, A) for compressing and decompressing, respectively, the compressible medium (L) are provided, by means of which the total volume (V 0 ) of the vessel (B) may be modified by a predetermined modification volume (”V) and in which the pressure means (DS, A) for measuring the modification internal pressure (P 2 , P 3 , P (t) ) in the vessel (B) in consequence of the compression and decompression, respectively, by the modification means (KA, A) are formed and in which there is provided a collection vessel (BA) connected with the vessel (B) via an opening (O) of the vessel (B) and a capillary tube (KA) for collecting a liquid measuring medium (F). |
