Adopts prepaid IC card design, users need to top up before using water, and the water supply valve will automatically close when overdue, effectively avoiding water fee arrears. It has a built-in anti-pry and anti-tamper sensor, which will trigger an alarm and lock the water supply when the water meter is illegally disassembled, ensuring equipment safety. It uses a built-in long-life lithium battery with a service life of up to 10 years, eliminating the need for frequent battery replacement. The LED digital display can display remaining water volume and cumulative water consumption in real time, allowing users to intuitively master water usage. The operation is simple without complex network configuration, and top-up and reading can be completed only by swiping the card.
The nominal diameter can be selected as DN15 and DN20, with threaded connection methods G1/2" (DN15) and G3/4" (DN20). The rated flow rates are 8m³/h (DN15) and 12m³/h (DN20) respectively, overload flow rates 10/15m³/h, working pressure 0.1-1.0MPa, protection grade IP65 suitable for daily splashing water. The overall size is 180mm*90mm*70mm, weight about 0.9kg, powered by built-in 3.6V lithium battery with a service life of up to 10 years. It supports contact IC card top-up, is compatible with the general one-card system of the property, and has low battery alarm and abnormal water usage reminder functions.
It is mainly applicable to water usage scenarios requiring prepaid management such as rental apartments, chain stores, employee dormitories and small shops. Landlords or property managers can distribute top-up cards in batches through the management system, and can master the water usage of each tenant/shop without going door-to-door for meter reading, effectively reducing the communication cost of water fee collection and improving the standardization of water management, suitable for small and medium-sized rental scenarios.
