I would obtain a preliminary report from a title company before you move the gas meters that are on your property to make sure that there is no easement for them to be there.The problem that I see is that if the meters have been on your property for more than five years, a prescriptive easement situation may have arisen allowing them to remain. I suggest that you consult with a real estate attorney about your matter after you have obtained the recommended preliminary report and have read it.
