Product overview

The NB-IoT IoT water meter adopts the latest IoT communication technology, features low power consumption and wide coverage, enables to solve communication problems in harsh environments such as water meter underground well, kitchens and bathrooms. The meter is equipped with a communication module, which can interact with the base station directly without the need of concentrator. It is simple to construct and has become the mainstream product in the water industry.

Our NB-IoT water meter can be classified into four types: integrated type, split type, vertical non-magnetic sensing and ultrasonic water meter according to different needs of customers.
