Prepaid Water Management Made Simple.Prepaid IC card system cuts manual reading costs by 80% and reduces unpaid bills by 30%, ensuring fair water allocation and revenue protection.
1.Prepaid management:
Users pay in advance, minimizing billing disputes and improving revenue collection.2.Offline operation:
Works without internet via IC card data transfer, ideal for remote areas.3.Tamper-proof:
Sealed structure with anti-magnetic triggers, auto-shuts valve upon tampering.4.Long-lasting:
≥8-year battery life with automatic shutoff when balance is zero.5.Easy retrofit:
Fits standard mechanical meter footprints for low-cost upgrades.1.Rural water supply systems
2.Multi-unit residential billing
3.Construction site water management
4.Campus water access control
