With the development of China's economy, pollution-free and safe gas has gradually entered people's daily lives. With the acceleration of urbanization in China, urban gas will develop towards high efficiency and pollution-free direction in the future. The 13th Five Year Plan period is a crucial period for China to comprehensively build a moderately prosperous society and realize the great rejuvenation of the Chinese nation. Energy development is facing unprecedented opportunities and challenges, and natural gas plays an important role in China's energy revolution. Under the policy guidance of the country's continued deepening of reforms, the development environment of the natural gas industry will undergo significant changes, and the global emphasis on environmental protection will lead to changes in the market size of the gas system. Many countries and regions have introduced policies to encourage the use of clean energy, and gas is a relatively clean energy source compared to traditional energy sources such as coal. Against the backdrop of energy transition, many regions are gradually transitioning from coal based energy supply systems to clean energy sources such as gas. The 2025 China (Xi'an) International Gas Application and Technology Equipment Exhibition aims to promote industry development by showcasing the latest technologies, products, and solutions in the domestic and international gas field. Through exchanges with industry colleagues around the world, it builds an efficient interactive platform for both supply and demand sides. With strong support from various institutions, the 2025 China (Xi'an) International Gas Application and Technology Equipment Exhibition will be held at the Xi'an International Convention and Exhibition Center from April 23-25, 2025. This conference will further expand the upstream and downstream industrial chain of the gas industry, showcase new technologies, equipment, and products in the domestic and international gas industry, gather global technology industry giants and innovative energy, analyze trends and pulse, deeply explore future technologies, innovate applications, and market development opportunities.

From May 17th to 19th, 2024, the Shanghai Metrology Exhibition will be held at the Pudong World Expo Exhibition and Convention Center in Shanghai, China. Dongfa Group will exhibit its latest research results. At the exhibition, after the chairman of Dongfa Group held a lighting ceremony, he announced the official launch of the "Smart Gas Comprehensive Supervision Platform", showcasing the convenient and efficient achievements achieved through municipal smart management of gas meters.

Relying on an intelligent gas meter, when a gas leak occurs in the kitchen, the gas alarm will automatically sound and the gas stove will automatically turn off... "" This system is just launched, and the core is an intelligent gas meter. "The staff explained that this intelligent gas meter project uses a 5G IoT intelligent gas meter as the indoor remote transmission terminal to achieve linkage control of the gas alarm and intelligent stove in the kitchen, in order to avoid gas leakage and explosion accidents. After installing the smart gas meter, residents can bind their card number with their mobile phones to connect with the gas meter. Intelligent gas meters also have functions such as remote meter reading, remote valve control, remote meter status reporting, and automatic tiered pricing. In recent years, the instrumentation industry has integrated advanced manufacturing, information, and intelligent technologies, increased efforts in independent technological innovation, broken through the bottleneck problem, and accelerated the digital, intelligent, and networked upgrading of the entire instrumentation industry. At present, the instrument and meter industry in Dandong has formed a distribution pattern with Liaoning (Dandong) Instrument and Meter Industry Base and surrounding parks such as Jiangwan Industrial Park as the core area, and surrounding urban areas such as Yuanbao and ZhenAn as auxiliary areas. The industry is mainly composed of multiple sub sectors such as industrial automation instruments and control systems, scientific testing instruments, commonly used instruments, and specialized instruments. In 2009, Liaoning (Dandong) Instrument and Meter Industry Base was established with the approval of the provincial government and recognized as a provincial key industrial base. In 2018, the base was awarded the national level demonstration base for new industrialization industry by the Ministry of Industry and Information Technology - Dandong, Liaoning (measurement and control instruments). From 2021 to 2023, more than 80 technological innovation projects have been implemented cumulatively.
