I reported a smell of gas from our meter. They were round amazingly

Yes, they work to a maximum of one hour to respond to a notification of
a potential leak.


The guy told me that they used goatskin bellows to measure the volume, and
over time they become impregnated with the smell of gas, and that would be
what it was.

I suspect he was pulling your leg or acting the goat :-)
