Large Caliber NB-IoT Valve-Controlled Water Meter Enhances Smart Water Management

As water utilities and infrastructure projects continue to adopt digital management technologies, large-caliber smart water meters are becoming increasingly important for remote monitoring and centralized operation.Yangzhou Wantai Electronic Technology Co., Ltd.provides the Large Caliber NB-IoT IoT Valve-Controlled Water Meter to support connected water measurement and remote management applications.

The product is a screw-wing, multi-jet IoT valve-controlled water meter designed around NB-IoT communication. It is intended for applications that require water measurement together with remote communication and valve management capabilities.

NB-IoT communication allows the meter to establish connectivity after installation, helping reduce the construction requirements associated with connected metering projects. The product also uses a short-time power supply mode, with power supplied to the communication module only while it is online, supporting low power consumption and extended service life.

Data is actively uploaded once per day by default, and the upload schedule can be configured according to management requirements. The system uses a B/S architecture, allowing access through a web browser, while a WeChat Mini Program can support functions such as water usage queries and online payment.

Remote valve control is another key capability of the product. The valve can be switched on or off remotely, providing water management operators with an additional tool for user management and centralized control. The meter is suitable for applications including rural water supply renovation and scattered urban users.

The product features Class 2 accuracy, a cast iron meter body, reed switch or non-magnetic sampling, NB-IoT communication and a DC 3.6V lithium battery. Its standard turndown ratio is R=100, with R160 and R200 available as options, while the stated battery service life is more than six years.

By combining large-caliber water measurement, NB-IoT connectivity and remote valve control, the meter provides a practical option for projects seeking more efficient remote data management and connected water supply operation.
