Nanjing Iron and Steel Group, founded in 1958. is a super large and key iron and steel enterprise in Jiangsu Province. In September 2000. "Nangang" was successfully listed on the Shanghai Stock Exchange. In 2010. Nanjing Iron and Steel Group Co., Ltd. was rated as China's top 500 manufacturing enterprises by China Academy of industrial economics, ranking 39th. The group has long been in the forefront of China's top 500 enterprises.

　　Nanjing Iron and Steel Group has a production capacity of 3 million tons of steel and 4 million tons of steel. At the same time, it has a complete production system and auxiliary system for mining, coking, sintering, pelletizing, ironmaking, steel rolling, etc. its business scope covers steel production, circulation, design, transportation, real estate, culture, tourism, international trade and other fields, forming a cross regional and cross-border industrial group with steel industry as the main business, financial capital operation and science, industry and trade as one.

　　The headquarters has long maintained in-depth cooperation with Nanjing Iron and steel group. The products are widely used in steelmaking, ironmaking, sintering, steel rolling and other production lines of Nangang group. Among them, the representative applications are the wireless remote electromagnetic water meter and the ultra long distance split converter electromagnetic flowmeter.

　　As a big water user, water metering is the core link of production and operation of Nangang group. The water measurement of steel plant has many difficulties, such as bad environment, wide distribution and high data requirements. Through in-depth communication with the site in the early stage, Sinier finally provided SEB series electromagnetic water meter for the group, which has the characteristics of ultra-low initiating flow rate (0.022m / s), high performance measurement, high reliability GPRS transmission, overall IP68 protection, high performance lithium battery power supply, maintenance free in the later stage, etc. In addition, the communication rate and mode of these water meters are specially customized for Nangang group. The equipment has been in stable operation for more than three years.

　　A batch of steel-making circulating water metering sites in Nangang group are of high temperature, strong interference, large dust and very bad environment. Therefore, the primary meter and converter need to be transmitted over a long distance of more than 200 meters. At present, the electromagnetic flowmeter market, no matter domestic or foreign brands, cannot achieve such a long transmission distance. In view of the above difficulties, Sinier has customized the ultra long distance split converter type se10 electromagnetic flowmeter for it. This product adopts the latest signal transmission technology developed by Sinier, which solves the problem well and obtains high recognition from users.
