Pre-paid IC card water meter is a family table ladder water price and water conservation and solved the old meter measurement, on the other hand also addressed without door-to-door copy meter, so the pre-paid IC card water meter type in today's community, property, a large number of need water meter of the user to select, choose the IC card intelligent water meter as the main measuring meter. So what should we pay attention to in daily use?

1. When the smart water meter is out of the home, it may lead to the change of the water inlet direction in the user's home, resulting in some dead water pipe sections in the home. The "dead water pipe section" behind this part of the billing water meter is either high in position or located in the prominent pipe section of the pipeline, which is easy to produce air bags.

2 for the newly installed table, in the installation of pipes in the home, the pipe should be laid along the corresponding Angle, reduce the pipe bending point, folding point, and the high point of the pipe design in a faucet often used, reduce the chance of air bag pipe network.

3. Install check valve in front of the table. Since the rotation of smart water meter is caused by pressure fluctuation and water compression, you can consider installing check valve, which can prevent water from flowing back. In this way, as the pressure increases, the water is compressed and the meter produces positive rotation; When the pressure is reduced, the check valve automatically closes and the meter does not turn. When the pressure rises again, as long as the pressure is not higher than the check valve pressure, the water meter will not turn; Water meter rotation is mainly because the water meter reciprocates for many times to accumulate a large amount of water, the installation of check valve can reduce the frequency of intelligent water meter rotation, and can well solve the water meter rotation problem caused by pressure fluctuation. However, due to the high residential water frequency, and the pipeline pressure fluctuation is small, so the check valve sensitivity is higher, quality requirements are higher.

4. Arrange the exhaust valve rationally according to the characteristics of the pipeline during the design, and remove the gas precipitated in the pipeline in time; When the new pipe or newly installed household table first water, should slowly open the valve, try to empty the air in the pipe, reduce the air content of the water.
