Large Caliber NB-IoT IoT Water Meter Supports Smarter Utility Management

As water utilities continue to improve digital meter reading and centralized management, large-caliber water meters with remote communication capabilities are becoming increasingly relevant for connected water supply projects.Yangzhou Wantai Electronic Technology Co., Ltd.offers the Large Caliber NB-IoT IoT Water Meter as part of its smart metering portfolio.

The product is a multi-jet IoT water meter designed to support remote water measurement and data transmission. It adopts NB-IoT communication, allowing communication to become available after installation while helping reduce the construction requirements associated with connected metering systems.

One of the key design considerations is energy efficiency. The meter uses a short-time power supply mode, meaning the communication module is powered only while it is online. This approach contributes to low power consumption and supports extended service life for long-term water management applications.

The meter actively uploads data once per day by default, while the upload schedule can be adjusted according to management requirements. This provides operators with greater flexibility when organizing remote meter data and planning centralized monitoring workflows.

For system access, the solution adopts a B/S architecture that can be accessed through a web browser. It also supports a WeChat Mini Program for functions such as water usage queries and online payment. The product is suitable for applications including rural water supply renovation and scattered urban users.

Technical characteristics include Class 2 accuracy, a cast iron meter body, reed switch or non-magnetic sampling, and NB-IoT communication. The standard turndown ratio is R=100, with R160 and R200 available as optional configurations. Power is supplied by a DC 3.6V lithium battery, with a stated battery service life of more than six years.

By combining large-caliber water measurement with NB-IoT connectivity, the product provides a practical option for projects seeking remote data collection, configurable reporting and more organized water utility management.
