Embodiment Construction

[0121] figure 1 Schematically shows a measuring system, which if required can be assembled modularly, which is suitable for very robust measurement of at least one measured variable of a medium (eg liquid, gas, steam, etc.) flowing in a process line not shown , in particular mass flow m and / or volume flow v and / or flow velocity u and / or other flow parameters, and for mapping this measured variable to at least one corresponding measured value X M . For this purpose, the measuring system includes at least one online measuring device for the flowing medium. The measuring device is formed with a suitable measuring transducer 100 and measuring electronics electrically coupled thereto at least intermittently. The on-line measuring device then comprises a measuring transducer 100 through which the medium to be measured flows during operation, and an electronics housing 200 in which measuring electronics (not described in detail here) are housed in electrical connection with the mea...

Abstract

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 measuringelectronics 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 measurementvariable. 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 baffle 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.

Description

technical field [0001] The invention relates to a measuring system for measuring at least one measured variable of a medium flowing in a process line, the measuring system having a measuring transducer and a flow regulator between the measuring transducer and the process line, wherein the measured variable Especially mass flow, density, viscosity, pressure, etc. Background technique [0002] In the field of industrial process measurement technology, in particular in connection with chemical automation or manufacturing process automation, in order to detect a measured variable describing a process and to generate a measured value signal representing this measured variable, measuring systems installed close to the process are used, which are installed directly in the On or in the process pipeline through which the medium flows. The measured variable to be detected can be, for example, the mass flow, volume flow, flow velocity, density, viscosity, temperature, etc. of such a l...
