The measuring system is placed in the course of a process line and is used to detect at least one measurement variable of a medium flowing in the process line. The system comprises a measuring sensor for this purpose with a measuring tube that conducts the medium to be measured and a sensor assembly which has at least one sensor element that reacts primarily to the measurement variable to be detected and which supplies at least one measurement signal that is influenced by the measurement variable by means of the sensor element or elements. In addition, the measuring system comprises measuring electronics that communicate with the measuring sensor and that use the measurement signal(s) to generate, at least intermittently, at least one measured value that represents the current measurement variable. The measuring tube of said measuring system has a smaller flow cross-section than a supply segment of the process line that is connected to the inlet side of the measuring system. The measuring system therefore also has a flow conditioner that is situated on the inlet side of the measuring tube, extends between said tube and the supply segment of the process line and has a lumen which tapers towards the measuring tube and through which the medium flows during operation. The flow conditioner has at least one inner edge which is situated upstream of the outlet end of said conditioner, projects into the lumen of the latter and against which the medium in the conditioner flows. |
