The split-type prepaid water meter accurately measures water consumption in both residential and commercial settings. Featuring a prepayment function and an advanced remote monitoring system, it delivers an efficient and user-friendly solution for modern water management.
With LoRa RF wireless technology, the meter simplifies the recharge process. Users can top up seamlessly through an intuitive interface. Real-time data transmission enables water supply departments to monitor usage trends, optimize resource allocation, and improve operational efficiency.
We strictly manufacture the split-type prepaid water meter in line with ISO9001 and ISO14001 standards. It meets the highest industry standards and ensures stable performance and long-term durability.
Functions
- Tamper Detection: Upon detecting magnetic interference, the meter will automatically close the valve. Service can only be restored by entering a clear tamper Token.
- Multi Tariff: Supporting configurable tiered pricing, the meter allows TOKEN-authorized setup of progressive rate tiers (up to 3 tariff steps).
- Event Log: Comprehensively logs tamper alarms (magnetic/valve events), decade-long consumption data (monthly/hourly), and enables real-time queries via short codes for balance/trend monitoring.
- Real-time Clock: Featuring a high-precision clock, the meter maintains accurate timestamps for all logged events and scheduled functions.
- Credit Alarming: The system triggers an alert when the remaining water credit falls below a user-defined threshold. The alarm value can be configured by entering a specific TOKEN code.
- Recharge Limitation: The meter prevents overstocking by rejecting recharge requests when the sum of remaining water and new recharge exceeds the preset limit.
- Emergency Overdraft: It supports emergency water access when the account balance runs out, and users can repay the overdrawn amount flexibly daily or monthly.
- Low Battery Alert: Displays warning for battery replacement, then auto-locks valve (with data backup) if unresolved.
