"...an examination of the gas meter at the house found that there was a large volume of gas entering into the home six to nine hours prior to the explosion."
How did they know that? Was it a electric meter?

Do the remote reading gas meters that are interconnected with the electric meter make real time (or at least maybe hourly) measurements possible? I have this set-up on my house. There is a wire that runs from the gas meter to the electric meter.
It used to be the person from the utility would just have to drive by the house and the information would download into a unit in the truck. Now it seems they've installed a lot of 2 way radio repeaters mounted on their own poles (wooden power poles) all over the area that I understand allows these readings to be taken without anyone driving around.
