1. High-grade water meter

The use of a meter with a high level of metering allows the meter to operate in a relatively large flow range, including small flows, and also fundamentally improves the meter sensitivity and metering capacity. Piston-type (also known as volumetric) water meters generally have a C or D rating, but they have a higher water quality requirement. Explanation: Most countries in the world require the use of water meters that meet the measurement level of Class B and above, and there are also calls for the elimination of water meters that measure Level A in the domestic industry. In the new international standards and international recommendations for water meters proposed here, flow meters based on electromagnetic or electronic principles for measuring water are also included in the water meters.

2. Remote Outdoor Reading

The combination of meter remote metering, meter reading system, and secondary meter matching with computer property management is promising because it improves meter reading methods, improves informationization, digitization, and automation. Concerns about the interruption and security of users who use water meters. This type of water meter is also used when implementing a household table in some parts of the country.

3. Prepaid water meter

The IC card water meter prepayment meter applies to the management system under the principle of “pay first and then use water”. In some areas of China, it is difficult to repay debts due to the difficulty of collecting water fees, and the use of pre-paid water meters has completely changed the way of meter reading and water use settlement, avoiding intensification of conflicts and increasing the technical content of water meter products. Property management companies welcome this product. The pre-paid water meter can collect water fees in a timely and reasonable manner, reduce water loss, reduce labor intensity, and avoid inconvenience and insecurity caused to users by meter reading activities. Typical products include IC card water meter (card or sensor type), TM card water meter, code exchange prepayment meter, etc.

4. Anti-backflow meter or two-way metering water meter

The current domestic water meters are generally single-flow water meters. Most of them can move around and reverse the cumulative number when they are in reverse flow (also known as reverse flow or reverse flow). The existing water meter seals do not prevent the water meter from flipping. There is a possibility of causing measurement disputes and cheating. Anti-backflow water meter can install the check valve at the entrance of the meter to seal the connecting pipe of the water meter and the water pipe together, preventing the possibility of cheating by manually pouring the water meter. The function of the bidirectional metering meter is that the metering mechanism of the meter is still cumulative and meets the requirements for metering accuracy during reverse flow. Note: The current national standards do not provide detailed provisions for backflow prevention or bidirectional metering. They only require that the meter be “understands accidental backflow and shows that this is countercurrent.”
