If the water's shut off at the street, and the valve is not dribbling. You
might be able to boil the water out of the copper, with a torch. I saw an
old plumber dry a copper pipe that way, once.

sounds like you will have no need for water over the winter.
if thats the case shut off water at curb, remove the valve and
fittings from the incoming water line indoors......
then siphon the remaining above floor water stuck in the line with
aquarium tubing....... suck on it if needed...
leave the meter and everything off till spring.
this way you have no need to heat the line or worry about a possible
freeze up, since there will be no water to freeze.....
