One of the key challenges is that steam often contains moisture, which can lead to two-phase flow conditions. This can significantly impact the accuracy of measurements. Vortex flowmeters are typically designed for single-phase flow applications. However, in real-world scenarios, especially with steam, two-phase flow (gas and liquid) is common. This makes it difficult to achieve precise measurements. Despite this, engineers and researchers continue to explore ways to improve the performance of vortex flowmeters under such conditions. **Challenges in Steam Measurement** During long-distance transportation, dry steam may lose heat and partially condense, forming wet steam. The structure of gas-liquid two-phase flow in horizontal pipes depends on the volume ratio of gas and liquid, as well as the flow velocity. In most cases, the amount of condensed water is small, so drain pipes are installed at the bottom of horizontal pipes to collect and remove condensate effectively. In high-speed flows, the fluid may form a circular pattern, with a liquid film along the pipe wall and a central gas core containing droplets. Gravity affects the distribution, causing the lower part of the pipe to have a thicker liquid layer than the upper part. In vertical ascending pipes, the two-phase flow can take various forms, such as bubble flow, slug flow, annular flow, or fiber-ring flow. In vertical descending pipes, the flow structures are similar but with different dynamics due to the direction of flow and higher liquid velocities. **Impact on Vortex Flowmeters** A major issue when measuring steam with a vortex flowmeter is the "leakage pulse" phenomenon. This occurs when the meter outputs fewer pulses than expected, even when the steam flow is stable. This is often caused by large droplets disrupting the formation of vortices behind the bluff body, leading to inaccurate readings. To prevent this, it's crucial to properly install steam traps upstream of the flowmeter. These traps help remove excess moisture from the steam, ensuring it remains as dry as possible before reaching the sensor. Proper placement of steam traps can significantly improve the reliability and accuracy of vortex flowmeters in steam applications. **About Henan Bo Rui Instrument Co., Ltd.** Henan Bo Rui Instrument Co., Ltd. is a trusted name in the instrumentation industry, offering a wide range of products such as electromagnetic flowmeters, vortex flowmeters, turbine flowmeters, and throttling devices.
