ZigBee-Certified Water Meter

The Elster V200 meters enable households to monitor their water usage wisely, while also giving utilities the ability to provide more efficient billing and better service to customers. The meters integrate into wireless home area networks (HANs), working seamlessly with other smart energy devices in the home to help households conserve water, electricity and other resources. A wireless ZigBee-to-IP hub communicates usage data back to the utility for billing and service applications.

The V200 combines Elster's proven measurement and smart meter technology, Ember's ZigBee chips and software, and a metering application developed with Freestyle's Microengine technology. As the meters are battery operated for easy maintenance and installation, the ultra-low power requirements of Ember's ZigBee chips were essential to the meter's design. The meters operate in "sleep" mode most of the time, awakening intermittently to communicate with the HAN and hub. Consequently, Ember's ZigBee technology enables the meters to operate reliably and securely for years using inexpensive batteries.

The V200 meters utilise the ZigBee Smart Energy (SE) version 1.1 profile to provide easy development, installation and operation, as well as interoperability with industry standard Advanced Metering Infrastructure (AMI) systems and other ZigBee SE devices. Elster can continuously enhance and update the meters using the SE profile's over-the-air update feature. 

Ember's ZigBee networking systems simplify the complexity of integrating embedded software, networking and RF for developing low-power, wireless products in the connected home, smart energy, and other remote monitoring and control applications.
