Measuring system with a flow conditioner arranged at an inlet of a measuring tube
First Claim
1. Method for registering at least one measured variable of a medium flowing in a process line, by means of a measuring system at least partially inserted into the course of the process line and including a flow conditioner connected to a supply segment of the process line, as well as a measuring transducer connected to the flow conditioner, said method including the following steps:
- allowing the medium to be measured to flow out of the supply segment into the flow conditioner;
accelerating the flowing medium in the direction of a longitudinal axis of the flow conditioner, and inducing at least one essentially stationary toroidal vortex within medium flowing in an inlet region of the flow conditioner in a manner such that a principal axis of greatest inertia of the at least one toroidal vortex essentially coincides with the longitudinal axis of the flow conditioner, and/or with a longitudinal axis of the measuring tube;
allowing the medium to be measured to flow through the at least one toroidal vortex, and allowing the medium to be measured to flow out of the flow conditioner into a measuring tube of the connected measuring transducer;
as well asproducing at least one measurement signal, influenced by the measured variable to be registered, by application of at least one sensor element reacting primarily to the measured variable and/or to changes in said measured variable.

Abstract
The measuring system is inserted into the course of a process line and serves for registering at least one measured variable of a medium flowing in the process line. 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.
