Both sensors communicate with measuring electronics of the system. The measuring electronics are operable to provide, based on temperature measurement, pressure measurement, and a numerical compensation factor a density measured-value, representing, a density of the flowing medium at a virtual density measuring point. The compensation factor corresponds with a locational variability of at least one thermodynamic variable of the medium, occurring along the flow axis of the measuring system and/or a locational variability of the Reynolds number of the flowing medium along the flow axis of the measuring system.Type: GrantFiled: June 30, 2008Date of Patent: June 12, 2012Assignee: Endress + Hauser Flowtec AGInventor: Rainer Höcker
