오하이오의 Canton은 물, 가스, 전기 시설을 위한 기술을 제공사인 Aclara Technologies LLC에서 제공하는 계량 송신부(MTUs)를 포함하는 STAR advanced metering infrastructure(AMI)로 개선할 예정이라고 발표했다.

새로운 기술은 시설이 거주 고객의 자원 보호와 수도요금 절감을 돕기 위한 중요한 계량 데이터를 수집을 도울 것으로 예상한다고 밝혔다. 18개월 후 Canton Water Department는 동시에 발생하는 계량 측정값을 전달하기 위해 쌍방 능력을 제공하는 3천300백의 MYUs와 2만5천 모델을 설치할 예정이다.

The city of Canton, Ohio, will receive an upgrade to its existing STAR®advanced metering infrastructure (AMI) network, provided by Aclara Technologies LLC -- a provider of intelligent infrastructure technologies for water, gas and electric utilities -- with the company's Series 3000 meter transmission units (MTUs).

Canton operates 41,500 metered accounts. The new technology will assist the utility with collecting critical meter data to help residential consumers conserve resources and reduce water bills. Further, over the next 18 months, the Canton Water Department will install 25,000 model 3300 water MTUs, which provide two-way capabilities to deliver time-synchronized meter readings that can provide a snapshot of system water consumption at a single point in time.

The 3300 water MTU uses the powerful STAR network radio frequency (RF) technology to transmit hourly, interval usage data and two-way communication to the utility. It supports up to 8-digit registers and delivers time-stamped reads on a time-synchronized network, allowing for advanced water distribution management. The 3300 MTU maintains a 20-year permanent battery and operates over FCC-licensed radio frequencies.

"Our MTUs ensure that all system clocks are set to the same time," said Steve Bruskiewicz, water product manager at Aclara. "Utilities can take a complete system read and use the data to reconcile the amount of water entering the system compared to the billable water consumed, thus identifying the probability of system leaks or meter tampering."

Upon completion of the residential phase of deployment, the Canton Water Department, which deployed Aclara's very first STAR System in 1997, plans to expand its Aclara STAR network to include commercial and industrial areas.
