What is that little meter attached to my siding?
Before the utility district had the system to read meters by radio, there was an outside meter reader attached to the meters inside. The inside meter transmitted the reading to the outside reader. This was convenient in that the meter readers no longer had to get inside your home to read the meter. However now that we have all radio read meters, if you still have a remote reader attached to your house, you can remove it and throw it away. It is no longer connected to an inside meter.
