Abstract

Pulses, including electrical waveforms, emitted light, and light reflected by a moving mechanical device, that are emitted by a standard utility meter may be received. A device may be controlled to vary its usage of the utility and that may be used to determine a usage per pulse. The usage per pulse information may be used to convert a pulse rate from a meter to emulate the pulse rate from another meter. Information about the other meter and/or services offered by the other meter may be provided to allow for emulation of the other meter.
