Although automatic meter reading (AMR) was invented about 100 years ago, AMR products have only been commercially available within the last 25 years, driven primarily by the utilities` need by to reliably read their customers` meters. Several of the early approaches to AMR were telephone-based, and market development was interrupted and redirected by telephone industry deregulation in the early 1980s. At that time, few people anticipated a similar redirection of AMR development from the deregula
The fundamental demands of the changing market remain consistent from state to state-improve customer service and reduce costs through competition. Applied to meter data collection and aggregation, should companies seek to grow their metering business in the increasingly eccentric markets or get out of meter reading altogether? The answer, of course, is cost of operation and the drive towards ever-greater efficiency.
Resi-MON, a wireless radio frequency-based, single-phase electric kWh submeter features compact, attractive housing, low installed cost (under $400) and easy interface to automatic meter reading systems. Models are available for single-phase 120V or 277V 2-wire inputs or 1- or 2-phase 120/208-240V 3-wire inputs. The kWh data is collected by split-core current sensors, which may be safely installed onto the electrical feeds of the circuit being monitored without shutting down the load. (www.emon.

Carolina Power & Light Co. (CP&L) selected the TransData MARK-V Series Electricity Meter equipped with a wireless modem for metering their major industrial accounts. This project marks the first major deployment of commercial and industrial electricity meters equipped with ARDIS wireless AMR technology by an investor-owned electric utility. The MARK-V meters are equipped with an internal Motorola wireless modem and proprietary internal antenna design housed completely under glass to communicate
The single chip modem allows long distance data communications over the power line. Intended for use by utility companies wishing to provide advanced billing and load management services (remote meter reading and load control), the product meets the EIC-61334 standard. The same chip can be used at either end of the data link by selecting client or server mode of operation. It sends data in short bursts around the zero crossing of the power voltage cycle to avoid most of the noise generated by mo
Itron and Southern California Edison (SCE) finalized and signed a contract for automatic meter reading (AMR) services. Under the terms of the contract, a mobile AMR system owned by Itron will be used to provide monthly consumption reads and direct access reads. Services are priced on a per-meter basis. The term of the contract is for 11 years with options to renew thereafter. Installation of the system is expected to begin in the third quarter of this year and will take approximately one year to
