Next, it is necessary to install a prepaid electricity meter in the consumer’s premises. Depending on the installation application, this could be a split meter, whereby the metering device is placed outside the consumer’s premises, for example, in a meter box or kiosk; whilst a user interface unit (keypad) is installed in the consumer’s house for them to interact with the meter. The split configuration is used in culturally sensitive environments, as well as where additional security is needed as the consumer cannot access the meter.
In other applications, the combo meter would be used. This is a combined device that incorporates both the metering device, as well as the consumer keypad, in one solution. The entire meter is then installed within the dwelling.
