摘要： 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.

The measuring system includes for such purpose a measuring transducer having a measuring tube serving for conveying medium being measured and a sensor arrangement, which has at least one sensor element reacting primarily to the measured variable to be registered, and which delivers by means of at least one sensor element at least one measurement signal influenced by the measured variable. Further, the measuring system includes a measuring electronics communicating with the measuring transducer and using the at least one measurement signal for producing, at least at times, at least one measured value instantaneously representing the measured variable. The measuring tube has, in the case of the measuring system of the invention, a smaller flow cross section than a supply segment of the process line connected to the inlet end of the measuring system. To this end, the measuring system further includes a flow conditioner arranged at the inlet end of the measuring tube and mediating between the measuring tube and the supply segment of the process line. The flow conditioner has a lumen tapering in the direction of the measuring tube. During operation, medium flows through the lumen of the flow conditioner. The flow conditioner includes at least one inner edge arranged upstream of its outlet end and protruding into the lumen of the flow conditioner. During operation, medium conveyed in the flow conditioner flows against the inner edge.
