What are the requirements for the straight pipe section of a vortex flowmeter? How to choose? The straight pipe section of the vortex flowmeter is required to be the first 20D and the last 5D (D is the inner diameter of the connected process pipeline). The length of the straight pipe section should be determined according to the specific installation scenario and process pipeline situation. Specifically, the requirements for the straight pipe section are as follows: The general requirements for the front and rear straight pipe sections of the vortex flowmeter are the front 20D and rear 5D (D is the inner diameter of the connected process pipeline), and the valve is generally designed on the downstream side of the flowmeter. This length setting is to create a stable flow state for the fluid before entering the flowmeter, reduce the impact of fluid flow disorder in the pipeline on the measurement results, and ensure the accuracy and stability of the measurement. Special equipment export installation requirements: When the flowmeter is installed at the outlet of the compressor, blower, or plunger pump, a valve needs to be installed on the upstream side of the flowmeter. Except for the upstream straight pipe section with a length of not less than 20D, it is best to install flow limiting or buffering devices on the upstream side. This is because the fluid flow state at the outlet of these devices is unstable, and there may be pressure fluctuations and uneven flow rates. Installing valves and flow limiting or buffering devices can further stabilize the fluid flow state and improve measurement accuracy. Different process pipeline requirements: For different process pipelines, the length requirements for the front and rear straight pipe sections are different. For example, when there are local resistance components such as elbows and valves in the pipeline, the length of the straight pipe section needs to be adjusted according to the specific situation to meet the measurement requirements. Installation requirements for source components: Temperature, pressure, and other source components should be installed on the downstream side of the vortex flowmeter, with different distance requirements. Generally speaking, the distance between the temperature source component and the flow meter should not be less than 5D, and the distance between the pressure source component and the flow meter should not be less than 3D. This is to avoid the impact of the source component on the fluid flow in the measurement area of the flow meter and ensure the accuracy of the measurement results. The selection method of straight pipe section depends on the installation scenario. If installing a vortex flowmeter in a general process pipeline with a circular edge, the length of the straight pipe section can be selected according to the standard of the first 20D and the last 5D. At the same time, it is necessary to ensure stable fluid flow inside the pipeline and avoid unstable flow states such as eddies and turbulence. If installed at the outlet of equipment such as compressors, blowers, plunger pumps, etc., in addition to meeting the requirement of upstream straight pipe length not less than 20D, it is also necessary to consider whether to install flow limiting or buffering devices based on the characteristics of the equipment and fluid flow conditions, and reasonably determine their installation position and size. According to the situation of the process pipeline,
