An instrument for measuring water flow. The cumulative flow of water is mostly measured. Generally divided into the volume of water meters and speed water meter two categories. The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.

Since 1825, the British Cruz invented the tank water balance with real instrument characteristics, the development of water meter are nearly two hundred years of history. The use and production of water meters started relatively late in china. In 1879, Li Hongzhang established the first water plant in Lushun for the navy. In 1883, British colonial Democrats established second water plants in Shanghai, and water meters began to enter china. With the construction of water plants in some coastal cities, in twentieth Century, the Shanghai Guanghua Machinery Factory (now Shanghai Guanghua Instrument Factory predecessor) imported some parts from abroad to produce water meters. For a long time, Yingfaride and other countries has been dominated by Chinese water meter water meter industry, these different varieties and specifications of the water meter, due to different standards, parts are not interchangeable, brought great difficulties to the maintenance of water tap water company.

After liberation in 1949, with the development of urban water supply industry, China's water meter industry has also developed accordingly. Since 1955, Shanghai, Beijing, Tianjin, Nanjing, Wuhan, Guangzhou and other cities have started production of water meters. At the beginning of 1980s, the water industry in the Machinery Industry Department of Shanghai Institute of industrial automation instrument organization, according to the international standard meter ISO4046 requirements of small caliber water meter and launched the eight national unified design, the integral impeller water meter pointer. Uniform design and plastic parts meter, to create favorable conditions for the organization of water meter specialized production, greatly promote the progress and development of Chinese water industry, to meet the development needs of the growing urban and rural tap water industry. In 1990s, China

Sustained rapid development of economic construction, water meter industry has also developed rapidly, the number of enterprises and total output has more than doubled, while a variety of intelligent water meter, meter reading system and other products have begun to rise. Accurate measurement can save resources, please select the water meter produced by regular manufacturers.
