Smart Water Meter


Meazon’s Ultrasonic wireless water meter is designed for accurate measurement of cold and hot water flow in residential and commercial establishments. It combines advanced technical features with robust wireless data communication proven technology such as Zigbee and NB-IoT, high accuracy and sensitivity. Its battery can last more than ten years while sending readings to the cloud every hour, and it can be replaced without removing the meter from its original location.

It is always connected to Meazon’s Cloud Gateway and through this can forward data to any 3rd party data visualization platform.

Optionally it can be equipped with a remotely managed valve for controlling water flow on demand. In a home, office or building it can communicate data to Meazon’s DinRail products that can act as a gateway towards Meazon’s cloud services. Combined with Meazon’s smart streetlighting controllers, it can add intelligence and flexibility in a Smart City, using the streetlight network as the data backhauling infrastructure. CE certified.
