MEASURING PROCEDURE AND MEASURING DEVICE FOR MEASURING PHYSICAL QUANTITIES OF NON-COMPRESSIBLE MEDIA

Measuring device for measuring the dynamic viscosity and the density as physical quantities of an essentially non-compressible measuring medium, with a vessel having a total volume, which is charged with a compressible medium and into which a measuring medium with a fraction volume may be introduced, and with pressure means for measuring an initial pressure and a modification internal pressure in the vessel, in which modification means for compressing and decompressing, respectively, the compressible medium are provided, by means of which the total volume of the vessel may be modified by a predetermined modification volume and in which the pressure means for measuring the modification internal pressure in the vessel in consequence of the compression and decompression, respectively, by the modification means are formed and in which there is provided a collection vessel connected with the vessel via an opening of the vessel and a capillary tube for collecting a liquid measuring medium.
