Abstract (en)
[origin: CA2692179A1] The invention relates to a measuring system for measuring a density of a medium flowing in a process line, said medium being variable regarding its thermodynamic state, especially at least being compressible, along an imaginary axis of flow of the measuring system. The measuring system comprises at least one temperatur e sensor that is located in a temperature measuring point and that primarily reacts to a local temperature, 9, of a medium flowi ng past, said temperature sensor supplying at least one temperature measurement signal that is influenced by the local temperature o f the medium to be measured, at least one pressure sensor that is located in a pressure measuring point and that primarily reacts to a local, especially static, pressure, p, of a medium flowing past, said pressure sensor supplying at least one pressure measurement signa l that is influenced by the local pressure, p, in the medium to be measured, and at least one electronic measuring unit that at least temporarily communicates with at least the temperature sensor and the pressure sensor. The electronic measuring unit generates at least temporarily an especially digital, density value, using the temperature measurement signal and at least the pressure measurement signal, said density value momentarily representing a local density,p, which the flowing medium has in an especially stationary, virtual density measuring point that is interspaced from the pressure measuring point and/or the temperature measuring point along the ax is of flow at a defined distance.
