Traditionally split meters have required hard wiring between the metering device and user interface keypad. Now, with Conlogs prepaid meter wireless user interface unit (wUIU), radio frequency is used between the devices, making installation simpler, better and faster. In addition, through the use of RF(radio frequency), users are assured of a working solution with no interference, that can operate comfortably at distances of typically 100 metres.
An added benefit is that the prepaid meter wireless user interface unit is fully compatible with Conlogs extensive range of split meters.
