The historical origins of water meters

From 1825, the United Kingdom g Luce invented the instrument features a truly balanced tank Meter Since the development of water meters for nearly two hundred years of history. The use and production of water meters in China got a late start. In 1879, Li as the cock-navy, in Port Arthur to create China¡¯s first water works. The British colonialists in Shanghai in 1883 to establish a second water plant, water began to enter China. With a number of coastal cities have to build waterworks, to the 20th century BC, when the Shanghai Guanghua Machinery Factory (now the predecessor of Shanghai Guanghua Instrument Factory), etc. some of the parts imported from abroad, the production of water meters. For a long time, Britain and France in countries such as Japan, Germany, has been dominated by China water meter water meter industry, these different varieties and specifications of the water meter complex, due to different standards, parts are not interchangeable, to the future maintenance of water meters of water companies has brought very difficult.

After the liberation in 1949, with the development of urban water supply, China¡¯s water meter industry has also developed accordingly. From 1955 onwards, Ningbo,Shanghai, Beijing, Tianjin, Nanjing, Wuhan, Guangzhou and other cities water company has started production of water meters. The 20th century, early 80s, water industry in the Machinery Industry Ministry, Shanghai, organized by the Institute of industrial automation instruments, the water meter in accordance with prevailing international standards, the requirements of ISO4046, to small-caliber water meter has introduced the eight indicators, the overall design of national unity impeller meter . Unified design and plastic parts of water meters, water meters for the organization of specialized production has created favorable conditions, greatly promote China¡¯s industrial progress and development of water meters, to meet the growing needs of industrial development in urban and rural water supply. The 20th century, 90 years, China¡¯s sustained rapid development of economic construction, water industry has also experienced rapid development, and total number of enterprises have more than doubled, while a variety of Intelligent water meter, Water meter reading system and other products have begun to rise.
