Product performance indicators comply with the national standard GB/T778-2007, the Ministry of Construction industry standard CJ/T133-2007 and the drinking water cold water meter safety rule CJ266-2008, which can be applied to the measurement and charging of water for residences, enterprises and institutions.

involves the vital interests of each user, this is an issue that everyone cares about. On the one hand, the price of a high-quality prepaid water meter is generally between 300 and 500. If the life of the water meter is too short, frequent replacement will make the user unacceptable; on the other hand, understanding the life of the prepaid water meter can avoid the loss caused by long-term use and inaccurate measurement, and it can also prepare the user to avoid prepayment The water meter is not replaced in time and cannot use water.

The service life of the water meter is closely related to the structure and materials used in the product, and is also affected by the installation and use occasions and water quality. The service life test in the laboratory cannot fully represent the actual usage. Generally speaking, the water meter housing is not easy to damage and can be used for a long time, but the internal movement is easily damaged or worn. The moving parts of the water meter (impeller, impeller box assembly, etc.) are usually made of relatively wear-resistant engineering plastic ABS material. After the water meter continuously tests the water, it is easy to damage the tip of the impeller shaft, the first gear of the impeller shaft gear and the transmission gear.

The actual service life of prepaid water meters is about 6-8 years. Because the water meter uses a large-capacity battery, combined with static zero power consumption technology, the battery life of the water meter is longer; the base shell of the prepaid water meter is all made of copper, and the surface is treated with corrosion and oxidation resistance, which provides another layer for the service life of the water meter Guarantee; the prepaid water meter adopts the country's higher water meter protection level IP68, on the one hand, it is waterproof, on the other hand, it can effectively prevent the water meter from being damaged by debris, and can work normally even in harsh environments with a lot of water and sediment. The above is the secret of the actual service life of prepaid water meters up to 6-8 years.
