Abstract
A measuring system includes at least one temperature sensor placed at a temperature measuring point, to deliver at least one temperature measurement signal influenced by the local temperature of a medium to be measured. At least one pressure sensor is placed at a pressure measuring point, and delivers at least one pressure measurement signal influenced by the local pressure in the medium. At least one flow sensor is placed at a flow measuring point, and delivers at least one flow measurement signal influenced by the local flow parameter. Measuring electronics calculates, based on the temperature measurement signal, the pressure measurement signal, and the flow measurement signal, at least one density measured-value, representing, instantaneously, a local density of the medium at a virtual density measuring point, the virtual density measuring point being spaced from the pressure measuring point and/or from the temperature measuring point along the flow axis.
