Xinjiang Tianfu Tiansheng Gas Co., Ltd. (a subsidiary of A-share listed company Xinjiang Tianfu Energy, stock code: 600509) is a core comprehensive energy service provider in Shihezi City, the Eighth Division of Xinjiang. With an annual gas supply exceeding 200 million cubic meters, it serves nine divisions and cities, including Shihezi, Shawan, Kuitun, and Yili. In 2022, the company launched an upgrade project for residential and commercial gas supply systems, focusing on retrofitting old communities and commercial complexes with advanced gas metering systems. Over 130 high-precision ultrasonic gas flow meters were deployed to build the first "end-to-end" smart gas monitoring network in the region.

Industry Pain Points and Challenges

Urban gas supply faces complex scenarios with multiple stringent requirements:

1. Metering Fairness: Accurate measurement of low flow rates (0.04-25m³/h) to avoid trade disputes.

2. Environmental Adaptability: Extreme temperature differences in Xinjiang (-30℃ to +45℃) pose challenges to instrument stability.

3. Safety Regulation: Real-time monitoring of micro-leaks (<0.1L/h) and pressure anomalies to ensure public safety.

4. Maintenance Efficiency: Decentralized terminal devices require remote diagnostics to reduce manual inspection costs.

Solutions

Tailored to a 130-kilometer pipeline network and 32,000 household terminals, our company designed a smart metering solution centered on Ultrasonic Gas Flow Meters (SUF-G Series):

Core Advantages of Ultrasonic Flow Meters:

• Wide Turndown Ratio (1000:1): Covers pipe sizes from DN25 to DN200, with a minimum start flow rate of 0.04m³/h (Qmin ≤ 1% Qmax), addressing the issue of "no measurement at low flow rates" in traditional diaphragm gas meters.

• All-Climate Adaptability: Built-in temperature compensation chip with a working range of -40℃ to +80℃. Winter anti-freezing design passes IP68 certification, withstanding dusty and dewy environments.

• Zero Pressure Loss Structure: No mechanical moving parts, with pressure loss <5Pa, reducing energy consumption at pressure regulating stations by 12%.

• Data Integrity: Built-in NB-IoT module uploads hourly data to the gas cloud platform, in compliance with the national standard GB/T 39841-2021 Ultrasonic Gas Meters.

Smart Maintenance Management:

• Remote Diagnostics: Ultrasonic probe self-inspection function (automatically reports signal strength and signal-to-noise ratio daily) to predict failures and generate work orders.

Implementation Results

• Civil Livelihood Protection: 130 devices cover 21,000 households and 2,600 merchants, reducing metering disputes by 98% year-over-year.

• Safety Upgrade: Intercepted 127 micro-leak events, with zero major safety accidents.

• Energy Efficiency Optimization: Pipeline pressure balance regulation reduces gas loss by 8%, saving over 3 million yuan in annual gas source costs.
