Brief Water Meter Development History in China

2023-02-01

In the year 1949, with the development of urban water supply, China's water meter industry also developed accordingly. Since 1955, water companies in Shanghai, Beijing, Tianjin, Nanjing, Wuhan, Guangzhou and other cities have successively started to produce water meters. In the early 1980s, under the organization of the Shanghai Industrial Automation Instrumentation Research Institute of the Ministry of Machinery Industry, in accordance with the requirements of the international standard ISO4046 for water meters at that time, the water meter with eight pointers and integral impeller was introduced for the small-caliber water meter. The unified design and plasticization of water meter components have created favorable conditions for the organization of specialized production of water meters, which greatly promoted the progress and development of China's water meter industry, and met the increasing needs of the growing urban and rural water industry. In the 1990s, China's economic construction continued to develop rapidly, and the water meter industry also developed rapidly. The number of enterprises and total output amount more than doubled. At the same time, various intelligent water meters, water meter reading systems and other products also began to emerge and develop.

Installation method:
1. The diameter of water meter should be determined according to the diameter of the installed pipeline. The installation location should avoid exposure to sunlight, flooding, freezing and pollution, so as to facilitate disassembly and assembly and card swiping.

2. The water meter should be installed horizontally (display side up).

3. Before new installation, sand, gravel, hemp and other debris in the pipeline should be removed to avoid water meter failure.

4. The direction of the arrow shown on the water meter should be consistent with the direction of the water flow in the pipeline.

5. If the water meter is installed at the water inlet end of the boiler, it is necessary to prevent the backflow of hot water and steam from the boiler and damage the internal parts of the water meter. It is better to install a check valve at the water outlet of the water meter.
