Liaoyang Automation Instrument Group Co., Ltd. is the parent company of Liaoyang Automation Instrument Group (referred to as "Liaoyi Group"), located in the central part of the Liaodong Peninsula. The company was founded in 1958 and is a member of the Flow Meter and Level Meter Professional Committee of the China Instrument and Meter Industry Association. With a strong industrial and material foundation, it is a comprehensive industrial company that integrates scientific research, production, self-development, system design, complete engineering, and foreign agency. The company has a strong technical force and consists of major departments such as research institutes, production departments, marketing departments, complete engineering departments, computer system engineering departments, and cabinet cooperation factories. The company has gathered a large number of scientific and technological talents as well as management talents. The verification method of using air instead of other gas flow meters developed by the company has won the second prize of Liaoning Province Science and Technology Achievement Award and filled the domestic gap. The company has advanced testing instruments and metrological calibration devices, and the provincial gas flow meter calibration station is located in our company to serve the whole province. The company adheres to the policy of independent research and development, foreign introduction, and comprehensive development through cooperation with colleges and universities. In recent years, many products developed by the company, such as impulse solid flow meters, intelligent electric float level transmitters, magnetostrictive level transmitters, radio frequency admittance level transmitters, V-cone tube flow meters, high temperature and high pressure, high pressure level gauges, coal mine safety warning control systems, etc., have been included in the national "Torch Plan" projects and have been awarded the "National New Product" award by the National Science and Technology Commission, the Ministry of Labor, the State Council's Introduction Intelligence Group, the General Administration of Quality Supervision, Inspection and Quarantine. The developed product has passed the "Measuring Instrument Prototype Test" of Liaoning Province's new measuring instrument product, and has reached the international level of similar products through testing. It has also been awarded the Special Equipment Manufacturing License of the People's Republic of China by the General Administration of Quality Supervision, Inspection and Quarantine. In particular, the successful application of impulse solid flow meters in the electrolytic aluminum industry has effectively solved the measurement problem of electrolytic aluminum dust removal and purification systems, which is the first of its kind in China. The development and production of high-pressure liquid level gauges have changed the previous situation where high-temperature, high-pressure, and high-pressure liquid level gauges needed to be imported, bringing convenience to the use of high-pressure liquid level gauges in domestic refining industries such as hydrocracking units. Technological progress has brought about rapid development of the company, with a registered capital of 98 million yuan and annual sales increasing by 50%. The products are exported to Eastern Europe, the Commonwealth of Independent States, and African countries. 56.2% of the employees in the company have a college or vocational school degree or above, and two of them are entitled to a lifetime technology allowance.
