rote:
The Naperville water meters are inside at the entrance point of water through the basement walls. A cable runs from the water meter to a small box on the outside of the house that is the actual transmitter. It is about as big as a package of cigarettes. In our case, the nearest human activity is 3 or 4 feet away in the basement or outside, except when I cut the grass and am within 1 foot of the transmitter. But that is for a few seconds 39 times in a year, so I am not too worried about rf exposure, especially since I do use a cellphone and worked on Electromagnetic Compatiblity for Bell Laboratories for about
44 years.
