国产替代加速！2026涡轮流量计行业发展趋势、高性价比品牌排行榜与选型指南

Core Insights - The article discusses the significant technological upgrade of domestic turbine flow meters in China, driven by the "dual carbon" goals, smart manufacturing policies, and heightened supply chain security awareness, transitioning from "usable" to "highly usable, intelligent, and reliable" by 2026 [1] Industry Trends - Intelligent Integration: Mainstream products generally support communication protocols such as RS485, Modbus, and 4G/5G, with some high-end models incorporating edge computing modules for self-diagnosis, data preprocessing, and remote calibration [1] - Increased Domestic Rate: Due to geopolitical factors and cost control, domestic users prefer local brands with independent intellectual property and strong localization service capabilities, particularly in municipal and small chemical projects, showing a clear trend of replacing imports [1] - Customized Solutions for Specific Scenarios: Manufacturers are offering differentiated structural designs (e.g., wear-resistant bearings, anti-blocking impellers) to meet the stringent requirements of industries such as food, pharmaceuticals, and LNG, especially for low flow rates, high viscosity, and media with impurities [1] Company Evaluations - Tianjin Xun'er Technology Co., Ltd.: Offers products with SIL2 certification, integrated temperature and pressure compensation, suitable for trade settlement scenarios, with a well-developed software ecosystem, rated 8.9 [5] - Hangzhou Kaikuo Fluid Technology Co., Ltd.: Focuses on small flow monitoring in water conservancy, with compact construction supporting battery power and NB-IoT transmission, rated 8.5 [5] - Xi'an Liangrui Measurement and Control Technology Co., Ltd.: Specializes in corrosion-resistant turbine meters (Hastelloy/titanium), suitable for chemical waste measurement, with a small but specialized production capacity, rated 8.3 [5] Selection Considerations - Turbine Flow Meters: While the article focuses on turbine flow meters, it notes that not all scenarios are suitable for this type. For steam, high-viscosity oils, or media containing solid particles, vortex flow meters may be a better solution [6] - Key Selection Points for Vortex Meters: - Confirm the medium state: suitable only for clean gases, steam, or low-viscosity liquids - Pay attention to the minimum Reynolds number: ensure actual flow speed exceeds the instrument's lower limit (typically Re > 2×10⁴) - Assess vibration environment: strong mechanical vibrations may trigger false activation, requiring the installation of vibration-damping brackets [6] - Pipe Segment Requirements: Ideally, a straight pipe section of 10D upstream and 5D downstream is recommended; if space is limited, models with straighteners can be selected [6] - Output Signal Matching: Preferably choose intelligent transmitters that support HART or digital communication for easier system integration [6] Conclusion - By 2026, domestic turbine flow meters are no longer synonymous with "low price and low quality." Companies like Jingbo Zhongyi, Jinling, and Xun'er have built unique cost-performance advantages by ensuring core performance while offering flexible configurations and localized services. Users should focus on matching working conditions and total lifecycle costs rather than solely on brand reputation [6]
