Product Feature

 Stable Operation in Humid Environments

Stable Operation in Humid Environments

The device meets the IP68 waterproof and dustproof standard, ensuring long-term stable operation in harsh and humid conditions. The internal mainboard is fully encapsulated with flexible sealing silicone, paired with a dedicated waterproof junction box, independent sealed battery compartment, and specialized waterproof battery, providing comprehensive waterproof protection from inside out.

Accurate Measurement

Accurate Measurement

Equipped with a mature and reliable wet-type rotary vane metering mechanism, the flow sensor is highly sensitive and efficient. It undergoes strict precision calibration and factory verification, ensuring accurate and stable measurement over long-term operation. This guarantees precise trade settlement and reliable water usage metering across various scenarios.

Prepaid Intelligent Management

Prepaid Intelligent Management

Built-in high-performance electric ball valve enables a smart prepaid water control mode. Users prepay for water, and water is supplied normally when the balance is sufficient; if the balance runs low, the valve automatically shuts off water supply. Once the balance is replenished, the valve reopens automatically. This ensures precise water usage control, eliminates manual billing and on-site valve operations, simplifies collection processes, and greatly improves water management efficiency.

Remote Automatic Meter Reading (AMR) & Smart Alerts

Remote Automatic Meter Reading (AMR) & Smart Alerts

Supports multiple wired and wireless communication modes, allowing scheduled automatic collection and upload of water usage data, synchronized with real-time device status. Remote valve control enables precise water supply management anytime, anywhere. The device can automatically report core parameters, including remaining battery, valve status, operational conditions, and network signal strength. Intelligent anomaly detection triggers alerts immediately in case of abnormal flow or device faults, quickly identifying potential issues, reducing manual inspection, simplifying maintenance, and achieving centralized, intelligent, and highly efficient water meter operation management.

Multiple Communication Options for Diverse Applications

Multiple Communication Options for Diverse Applications

The device is compatible with mainstream industry-standard interfaces and universal communication protocols, equipped with an M-Bus standard interface and supporting dual protocols EN1434-3 and Modbus RTU for strong compatibility. It also supports 4G, NB-IoT, and LoRaWAN wireless communication, providing flexible wiring and easy networking, suitable for residential communities, industrial parks, and diverse installation environments, fully meeting the requirements of different projects for networking and data transmission.

FAQ

How does a prepaid water meter achieve automatic billing?

The device uses a high precision metering module to collect users’ water consumption data in real time and automatically calculates water charges based on predefined pricing rules.

How can users recharge their water accounts?

Depending on the project configuration, users can recharge their water accounts through management platforms, mobile apps, self-service terminals and other supported payment channels.

Does the prepaid smart water meter support remote valve control?

Yes. Authorized administrators can remotely control valve operations through the management platform, including remote valve opening and closing, valve closure due to insufficient balance, and water supply restoration after recharge.

Can the prepaid water meter terminal integrate with existing water management systems?

Yes. The terminal supports standard communication protocols and data interfaces, and can be integrated with smart water management platforms, property management systems, energy management platforms, etc.

How does the IoT smart water meter system prevent abnormal or unauthorized water usage?

By combining intelligent metering and data analysis capabilities, the system can monitor abnormal water usage behaviors, such as continuous water flow and unusual consumption patterns, and send alerts through the management platform for timely response.
