Itron and Invensys integrate AMR and solid-state metering technologies

Spokane, Wash., September 23, 2002 — Itron Inc. has partnered with Invensys Metering Systems – North America Inc., part of Invensys PLC, to offer a solution that integrates Itron’s 51ESS ERT AMR technology with the new Invensys solid-state, single-phase residential iCon meter.

This technology, which is now commercially available, enables Itron handheld and mobile systems to receive kWh consumption billing data from the iCon meter register. In addition to the kWh consumption billing data, the Itron fixed network system also retrieves interval data from the 51ESS ERT.

The iCon meter with 51ESS ERT technology supports self-initiated transmissions of standard kWh consumption and interval data information, which enables utilities to calculate time-of-use, demand and load profile data that can be used for billing, energy management and demand response programs.

The iCon meter with 51ESS ERT also transmits tamper detection notices such as meter removal and meter inversion.

“Our commitment to provide open-architecture solutions that enable our customers to keep their advanced meter technology options open, is a key reason why Itron’s AMR system architecture is the most widely used in the utility industry,” said Doug Staker, vice president of Itron’s Mobile and Network Telemetry Systems Group.

“This integration of our industry-leading advanced automation technology with a low-cost, solid-state residential metering platform from Invensys provides our electric utility customers with new choices and capabilities to support their advanced meter data collection strategies.”

“The iCon meter provides the ideal platform for the 51ESS ERT,” said Arlin Rummel, iCon System Program Director for Invensys Metering Systems. “The iCon meter was specifically designed for integration of advanced communication technology. The ERT technology has been incorporated into the iCon meter with careful consideration of cost, ease of replacement and retrofit. The iCon meter is recognized for its superior performance. It is field proven and compliant with the most stringent industry requirements for a revenue class electricity meter.”

“The 51ESS ERT radio performance is optimized for the iCon meter. Also, it does not require any programming by the customer. The iCon meter with 51ESS ERT is fully compatible with existing Itron walk-by, drive-by, and fixed network systems. The iCon meter’s superior performance coupled with the ERT makes the meter a very capable energy metering solution,” said Bill Mazza, Manager of Communication Systems.
