Reading Your Meter

Nicor Gas automatically reads residential, commercial and industrial meters. This is possible due to meters that have been upgraded with two-way communications devices that enable meter reads to be obtained without the need for a field visit. A small percentage of meter reads are still obtained by a meter reader that visits your home or business notating the amount of natural gas you use and generating your utility bill.
