Abstract
A measuring system precisely for measuring the density of a medium flowing in a pipe line. The measuring system comprises a temperature sensor and a pressure sensor. 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.
