The waterproof card-type water meter is a new type of water meter that utilizes modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption, transmit water usage data, and conduct settlement transactions. Compared with traditional water meters, which generally only have the function of flow collection and mechanical pointer display of water consumption, it represents a significant advancement. In addition to recording and electronically displaying water consumption, smart water meters can also control water usage according to predefined agreements.

Performance Features:

◆ Can record and electronically display water consumption;

◆ Can control water usage according to predefined agreements, automatically complete the calculation of water fees based on tiered pricing, and also store water usage data;

◆ Data transmission and transaction settlement are conducted via IC cards, offering the advantages of convenient transactions, accurate calculations, and the ability to utilize banks for settlement.

Technical Parameters:

Main Technical Performance:

◆ Operating Environment Temperature: 0-60°C

◆ Relative Humidity: ≤85%

◆ Measured Water Temperature: Cold water meter 0-50°C; Hot water meter 0-90°C; Pure water meter 0-35°C

◆ Operating Pressure: 0.02MPa~1MPa

Background Technology:

With social progress, people's living standards are increasingly higher, and the quality of many daily necessities has also improved, including commonly used water meters. Generally, a water meter is defined as a flow meter that uses the direct mechanical movement process of an active wall volumetric measurement chamber or the effect of water flow velocity on an impeller to calculate the volume of water flowing through the pipeline. In simple terms, it is an instrument for measuring water flow, mostly for cumulative water flow measurement. The internal structure of a typical water meter can be divided into three main components from the outside to the inside: the casing, the sleeve, and the inner core. The inner core is divided into upper, middle, and lower layers. What is seen through the glass window is the upper layer, which only has pointers and a dial. The key is the lower layer, where there is a plastic wheel with many plastic blades on its edge, called the impeller. This type of water meter is called a velocity water meter, but it requires high water quality. It is an instrument for recording tap water consumption, installed on water pipes. When the user uses water, the pointer or digit wheel on the meter rotates to indicate the amount of water used. However, some have become increasingly intelligent, utilizing microelectronics technology and smart IC card technology to measure water consumption. Currently, almost all prepaid water meters on the market have not undergone waterproof treatment, only moisture-proof treatment. However, it has been found that some customers need to install water meters in underground drainage ditches, where they may be submerged by rainwater during the rainy season, causing the water meters to malfunction.
