An apparatus for measuring density of media moving through a conduit included therein comprises one or two vibrating sections under two different flexural vibrations vibrating at two different natural frequencies which are functions of the stiffness of the vibrating sections of the conduit, density of the media moving therethrough and viscosity of the media as well as the viscosity of the ambient air surrounding the vibrating sections of the conduit. A mathematical combination of the two different natural frequencies of the vibrating section or sections of the conduit eliminates the dependence thereof on the viscosities and determines the density of media accurately independent of the viscosity.
