An improved meter and its operation is described. The meter can be a part of a larger automated meter reading process that allows for remote reading of the meter though power line communication. Using a microcomputer core, the meter processes incoming analog data and can calculate several relevant data values need by utility providers. The meter can also be used to monitor and detect tampering dry connect/voltage free devices, such as gas and water meters, connected to the meter.

Method and apparatus for an electric meter

A receiver particularly suited for an M-BUS is described. During transmission, the receiver is disabled. After each transmission, nodes and states in the receiver are set to prepare the receiver to receive a signal. Once data is sensed, a feedback loop clips the input signal to the receiver to limit the swing of the input signal. The line of the power supply at the lower potential is modulated, rather than modulating the line at the higher potential, for the transmission of data.

Receiver particularly for a meter-bus

A power supply providing current interruption based on the energy from the supply over a sliding window of time is disclosed. The output current from the supply is periodically reestablished.
