COMMODITY METER
A commodity meter. The meter includes a power/meter circuit board, a communication circuit board, and an antenna. The power/meter circuit board is configured to electrically sense a plurality of parameters of electricity flowing through terminals of the meter. The communication circuit board is configured to transmit one or more commodity parameters received from the power/meter circuit board. The antenna is coupled to the communications circuit board and positioned within the meter.
1 . A commodity meter, the meter comprising:
a meter base;
a cover attached to the meter base; and
self-contained within an internal volume formed by the meter base and the cover,
a power/meter circuit board configured to electrically sense a plurality of
parameters of electricity flowing through terminals of the meter,
a communication circuit board configured to transmit one or more commodity
parameters received from the power/meter circuit board, and
an antenna coupled to the communications circuit board.
2 . The commodity meter of claim 1 , wherein the communication circuit board includes an RF transceiver sub-assembly.
3 . The commodity meter of claim 2 , wherein the RF transceiver sub-assembly includes a communication microcontroller, a spread spectrum processor, and an RF transceiver.
4 . The commodity meter of claim 1 wherein the cover includes a transparent section.
5 . The commodity meter of claim 4 , further comprising an LCD sub-assembly having an LCD, wherein the LCD can be viewed through the transparent section of the cover.
6 . The commodity meter of claim 4 , further comprising a common backplane that couples the power/meter circuit board, the communication circuit board, and the LCD sub-assembly, wherein the position of each is interchangeable.
7 . The commodity meter of claim 1 , further comprising a pair of terminals extending from the base, the pair of terminals configured to complete a connection between a power line and the meter.
8 . The commodity meter of claim 1 , further comprising a network module.
9 . The commodity meter of claim 8 , wherein the network module is replaced with a second network module to change a data communication network.
10 . A commodity meter, the meter comprising:
a meter base;
a cover attached to the meter base; and
self-contained within an internal volume formed by the meter base and the cover,

parameters of electricity flowing through terminals of the meter,
a communication circuit board configured to transmit one or more commodity
parameters received from the power/meter circuit board,
an antenna coupled to the communications circuit board, and
means for receiving the power/meter circuit board and the communication circuit board, and for allowing interchangeability of position of the power/meter circuit board and communication circuit board.
11 . The commodity meter of claim 10 , further comprising an LCD sub-assembly and a network module.
12 . The commodity meter of claim 11 , wherein the receiving means is further for receiving the LCD sub-assembly and the network module.
13 . The commodity meter of claim 12 , further comprising means for replacing and interchanging the power/meter circuit board, communication circuit board, the LCD sub-assembly, and the network module.
14 . A method of manufacturing a commodity meter, the method comprising:
inserting a communication circuit board in the meter;
