What are the ordinary water meters

Water meters belong to mechanical cold water meters, and some water meters belong to mechanical cold water meters equipped with electronic devices, commonly known as ic card water meters or card water meters. In fact, there are many kinds of water meters.

1, according to the working principle and structure, water meters can be divided into: mechanical water meters and water meters with electronic devices; Water meters with electronic devices can be divided into electronic water meters and mechanical water meters with electronic devices.

2. According to the working water temperature, water meters can be divided into cold water meters and hot water meters;

3. According to the accuracy grade, the water meter is divided into 1 grade and 2 grade;

4. According to the nominal caliber, water meters can be divided into small caliber water meters and large caliber water meters; Small-caliber water meters are DN40 (φ 40 mm) and below, also known as civil water meters; There are also large-caliber water meters, also known as industrial water meters.

5. According to the installation method, the water meter can be divided into horizontal installation and vertical installation;

6. According to whether the working pressure can work under 1MPa, water meters are divided into ordinary type and high pressure type.

The above are several common classification methods, of course, according to whether the counter is immersed in water, the indication form of the counter, the amount of water flowing to drive the impeller and so on.
