Chongqing Hongjie Technology Co., Ltd. is located in Beibei, an instrument industrial base on the banks of the Jialing River at the foot of Jinyun Mountain in Chongqing. The company integrates instrument production, technical services, and software development, specializing in the production of high-quality flow meters, intelligent instruments, industrial automation control systems, and energy management system software development. The company has strong technical strength, with several professional technicians with senior technical titles who have participated in the formulation and revision of national standards for intelligent gas flow meters. The company has excellent production and processing equipment, advanced and mature production processes, and complete testing equipment. Relying on technological advantages and refined management, it provides stable and reliable products and comprehensive services to its customers. The throttling devices produced according to the ISO5167 standard are widely used in industries such as petrochemicals, metallurgy, military, aerospace, machinery, and power. The company is engaged in the application development of industrial automation control systems and energy metering management systems. Distributed control systems are computer control devices with microcomputers as the core. Its basic characteristics are decentralized control and centralized management. It embodies the concept of "decentralized control and centralized management", reducing the risks caused by centralized control. Risk diversification is reflected in the early DCS where a control station or control unit only contained (8-16) control loops, often requiring the configuration of multiple control units to meet the overall control requirements of a single unit or production facility on site. High quality after-sales service is the foundation for ensuring the reliable operation of products, and it is also a consistent commitment of Hongjie people to users. High level technical talents, strict archive management, comprehensive technical training, and specialized teams are the specific guarantees of our commitment.
