Problems solved by technology

The disadvantage of using such a pressure line is in particular that, due to the opening in the pipe wall, additional measures are required to reseal the pipe fitting as well as the pressure line in a reliable and leak-free manner
Furthermore, another disadvantage is that such pressure lines themselves can influence the measurement or can cause measurement errors

Embodiment Construction

[0035] figure 1 , 2 , 3A, 3B, 4A or 4B illustrate an exemplary embodiment of a measurement system for measuring at least one measured variable of a fluid flowing in a pipeline, which may optionally also be measured over time Varying, in particular, flow parameters such as, for example, the flow velocity v and / or the volume flow V'. The pipe can be designed, for example, as a plant part of a bottling facility of a heating network or a turbine circuit, so that the fluid can be, for example, an aqueous liquid, steam or, for example, also condensate discharged from a steam line. However, the fluid can also be, for example, (compressed) natural gas or biogas, so that the pipeline can also be, for example, a natural gas or biogas plant or a component part of a gas supply network.

[0036] In order to detect the at least one measured variable, the measurement system comprises a transducer 10 arranged or designed to cause fluid to flow in the direction of flow during operation and / o...

Abstract

The tube is used to conduct a fluid flowing through the tube in a specified flow direction and for this purpose comprises a tube wall (110), which encloses a lumen (100*) of the tube, and an interference body (120), which is arranged within the tube but is nevertheless connected to the tube wall at an inner face of the tube wall facing the lumen. In the tube according to the invention, the tube wall has a maximum wall thickness (smax) of more than 1 mm and at least two mutually spaced sub-segments (100-1, 100-2) with a respective wall thickness (s110-1, s110-2) that deviates from said maximumwall thickness (smax), wherein the sub-segment (100-1) is positioned upstream of the interference body (120) in the flow direction, and the sub-segment (100-2) is positioned downstream of the sub-segment (100-1) in the flow direction.

Description

technical field [0001] The present invention relates to a tube suitable for a transducer, and to a transducer formed by such a tube for detecting a measured variable of a flowing fluid, or to a transducer formed thereby for measuring a variable in a pipeline A system for measuring the flow parameters of a fluid flowing in it. Background technique [0002] In process, measurement and automation technology, measuring systems, usually designed as vortex flowmeters or differential pressure flowmeters, are used for measuring fluids flowing in pipelines, especially fast-flowing and / or hot gases And / or a flow parameter of a fluid flow having a high Reynolds number (Re) or having a volume or mass flow rate corresponding to the corresponding flow velocity (u), eg flow velocity and / or volume flow. Examples of such measuring systems are known in particular from JP-A 0682281, US-A 2017 / 0328750, WO-A 2008 / 061551, WO-A 2009 / 158605 or WO-A 2013 / 180843, and in particular also by the applic...
