Ember enables first ZigBee-certified water meter
Elster and Freestyle have integrated Ember’s ZigBee System-on-Chip and ZigBee PRO networking software into the latest Elster V200 digital water meter to serve global markets. The V200 is one in a series of Ember-enabled smart meters from Elster, with ZigBee smart meters for gas and electricity also in development.
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 effortlessly 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 utilize 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.
"Elster and Freestyle Technology are leading the change to bring tailored metering solutions that comply with the European and other regulatory directives for smart gas and electricity metering," said Andy Man, Ember’s vice president of sales for the Asia-Pacific region. "This partnership will enable the companies to continue to develop smart metering solutions for different markets across the globe."
