REX meter

LaPine, OR, U.S.A. --- (METERING.COM) --- February 9, 2007 – U.S. utility Midstate Electric Co-op is expanding its EnergyAxis System, supplied by Elster, a provider of metering solutions. Midstate Electric initially installed over 500 REX meters during the trial stage that began in October 2005. It is now moving into the first phase of expansion and is installing approximately 100 REX meters per month on new construction. It is also implementing a plan to replace all existing meters with REX meters over the coming years.

Midstate Electric's EnergyAxis System uses A3 ALPHA meter collectors with an RS-232 interface and INET IP-addressable radios to provide an RS-232 over Ethernet communications protocol for system data collection. In addition to monthly billing reads, REX meters are read on a daily basis for load profile data. Midstate Electric uses data such as system voltages, peak demand, and customer usage to look at transformer loading and determine where improvements to the distribution system are needed.

Midstate Electric said it selected Elster's EnergyAxis System because it was familiar with the system's communication technology and because it had performed well in a 2005 winter test.
