How do I prevent water meter from freezing?

[Zopkios]

Attached is a photo of my water meter, installed on the inside of an exterior wall.

During the winter months, I am living elsewhere. So there is no water movement.

Because the basement is unheated, the water meter has been a casualty of freezing even though the water main is always shut off when I am not here.

Because I am not willing to heat the basement for the sole purpose of protecting the water meter from freezing and bursting, I am wondering if installing a drain valve in the circled area would solve the problem since it would ensure there isn’t residual water in the meter or connecting supply lines.

I’ve considered installing self regulating heat tape but because it is not approved for use in inside walls, that alone is a disqualifier. Still, if I removed the hinged door, the area would be pretty well open.

Another idea might be a meter insulation jacket such as the one by ABT Water Store - https://store.abtwater.com.

Whatever method I end up trying, I have to be reasonably certain it will be successful. I have already gone through two meters and don’t want to be in trouble again with the water authority.

So what are your thoughts and suggestions?

If your elsewhere it might be best to have a drain off fitted after the meter so you can winterised eg drain all the water out etc

If it's just the meter that is getting frozen and damaged rather than the rest of the pipe work how about fitting isolation valves either side of the meter and within that a drain cock so you can isolate the meter ss well as drain any water from the meter without having to drain down the whole system?

Electric Tubular heater with a thermostat positioned directly below it?

Why don't you check with the water authority/the heat tap manufacturers whether they consider that to be 'inside a wall'? My feeling is that, if there's a door, the area accessible from that door is a cupboard and not 'inside a wall'.
