An electronic electric meter for use in a networked automatic meter
reading environment. The electric meter retrofits into existing meter
sockets and is available for new meter installations for both single
phase and three phase electric power connections. The meter utilizes an
all electronic design including a meter microcontroller, a measurement
microcontroller, a communication microcontroller and spread spectrum
processor, and a plurality of other communication interface modules for
communicating commodity utilization and power quality data to a utility.
The electric meter utilizes a modular design which allows the interface
modules to be changed depending upon the desired communication network
interface. The meter measures electricity usage and monitors power
quality parameters for transmission to the utility over a two-way 900 MHz
spread spectrum local area network (LAN) to a remotely located gateway
node. The gateway node transmits this data to the utility over a
commercially available fixed wide area network (WAN). The meter also
provides direct communication to the utility over a commercially
available network interface that plugs into the meter's backplane or bus
system bypassing the local area network communication link and gateway
node.
