Old style meters will withstand being submerged, for a while at least, as they are gas-tight, so, in theory, no water can get in. The weak spot is the display, which usually ends up full of condensation, which makes them unreadable.

Smart meters have electronics and batteries inside, so are far less tolerant of moisture.

The meter is the responsibility of your supplier. Probably best to report it to them and they should try to rectify the situation.

My trick was to gently tap the index which was unreadable with  condensation and it would eventually fall away and clear.
