Nanchang intelligent water meter manufacturers wholesale price implementation of tiered water price requirements to achieve one meter per household and meter reading to the household, which will inevitably bring work pressure to the water supply enterprise. The wool comes from the sheep, so the water price naturally has to rise. "Currently, most newly built communities use prepaid IC card water meters. It is difficult for communities using this type of water meter to implement tiered water prices, unless they spend more money to change each household's water meter to an intelligent water meter. Our city has issued relevant policies for eight years but few communities have implemented them. A water meter is a meter named after its use medium and purpose, which is used to measure the cumulative volume of clean cold water or hot water flowing through the pipeline. In flow meters, water meters have the characteristics of simple structure, wide flow range, small pressure loss, easy installation and maintenance, relatively low cost, etc., so they are widely used in residential water metering and industrial water metering, and are one of the widely used and important meters in flow measurement.
Nanchang intelligent water meter can be classified according to measurement principles, measurement methods and structural forms, measurement purposes, measurement media, measurement pipe diameters, display methods of indication values, etc. For example, according to the medium temperature, it can be divided into cold water meters and hot water meters, with a water temperature of 30°C as the dividing line; classified by measurement principle, it is called mechanical water meter, water meter with electronic device and electronic water meter, mechanical water meter can generally be divided into velocity water meter and volume water meter. Typical velocity water meters include rotary vane water meters and rotor water meters; typical volume water meters include rotary piston water meters, which are mainly used for household drinking water measurement in China.
Key indicators
1. Accuracy class
The accuracy class of cold water meters is divided into Class 1 and Class 2. Accuracy class 1 is only suitable for water meters with a common flow rate of ≥100m3/h; accuracy class 2 is suitable for water meters with a common flow rate of <100m3/h, and is also suitable for water meters with a common flow rate of ≥100m3/h.
Hot water meters are divided into A, B, C, D four measurement levels according to small flow rate and dividing flow rate.
