1. Recommended brand of ultrasonic measuring instruments for the construction of a natural gas network. For the ultrasonic measuring instruments used for the construction of a natural gas network, the appropriate brand can be selected according to the project conditions and budget. The specific recommendations are as follows:

1. Domestic brand recommendations: (1) Mainstream brands suitable for long-distance trunk lines and urban gas gate stations Chongqing Chuanyi: a leading state-owned enterprise in the domestic instrument and meter industry, with a national level technology center and independent research and development of multi sound Lutuan Ludao ultrasonic algorithm. The product accuracy range is ± 0.5%~± 1%, with explosion-proof, wide temperature, and anti-interference capabilities. It has passed international certification and has been applied to major projects such as the West East Gas Pipeline and the National Pipeline Network. The localized service response is fast and the after-sales system is perfect. Chongqing Qingtian Teke: a technology leader in the field of gas ultrasonic flow meters in China. It adopts the principle of ultrasonic time difference method, integrates flow measurement, volume correction, and data remote transmission, with a measurement accuracy of ± 0.5%, a range ratio of 1:100, and is suitable for 0.1-30m/s Wide flow rate range, globally selected key components, capable of long-term stable operation under -40 ℃~85 ℃, high pressure, high humidity, and explosion-proof scenarios, with a full bore pressure loss free design, built-in temperature and pressure compensation module, supporting multiple remote transmission methods, complying with relevant national standards, and can issue

authoritative calibration certificates. It is widely used in urban gas gate stations, long-distance pipelines, and other scenarios. Tianxin Instrument (under Jinka Intelligent): a well-known leader in the domestic gas metering field, a core tire supplier for natural gas trade metering, and its core product TUS gas ultrasonic flow or peak gauge meets relevant international standards. （2） A cost-effective brand that adapts to the renovation of old pipeline networks and temporary monitoring Dalian Yister: a leading brand of external clamp type gas ultrasonic flowmeter, with the highest market share both domestically and internationally. The YST305 series adopts nano coating sensors, with an accuracy of ± 1.2% in high humidity and dust environments. It pioneered the dual-mode adaptive technology of "time difference method+Doppler method", which can automatically adapt to complex flow states without breaking pipes or stopping production for installation. The maintenance cost is 30% lower than imported brands. It has 20 direct service points nationwide and an 8-hour emergency repair response time, with outstanding cost-effectiveness.

II. Recommended International High end Brands 1 Siemens: Global process automation giant, SITRANS FUS series adopts multi-channel design with an accuracy of ± 0.5%, supports multiple bus protocols, and has strong anti-interference ability. It is suitable for high-end occasions such as large-scale petrochemical, power, and natural gas transmission, but it is expensive and has a long delivery cycle. Emerson: Rosemount series multi-channel ultrasonic flow meters dominate natural gas long-distance pipelines and urban gate stations, with an accuracy of ± 0.2%, online diagnostic function, and ext
