With the implementation of "one household, one meter," the number of water meters managed by water supply companies has sharply increased. Installing prepaid water meters is a choice for water supply companies to strengthen modern management and improve service levels. The use of prepaid water meters also avoids the many inconveniences brought to customers by manual meter reading and on-site billing, and all historical water purchase data can be saved for customer inquiries. 【Especially for families with elderly members or those with mobility difficulties, using such water meters greatly reduces their burden! At the same time, it does not disturb users' normal daily lives, as there is no need for on-site meter reading!】

Prepaid water meters implement the principle of commodity exchange, allowing water to be bought before it is used, completely reforming the traditional water fee collection model and fully reflecting the commodity attributes of water. Customers can purchase and use water according to their actual needs, planning their water usage without incurring late fees due to unpaid bills, thus avoiding unnecessary expenses.
