ABSTRACT:
A measuring system includes a measuring transducer having a measuring tube serving for conveying medium and a sensor arrangement and 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, 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.
