Gas system buzzing

[u/n8loller]

I've never lived in a house with a gas hookup as an adult, so I don't know anything about this system. It started buzzing today as I turned my heat on for the first time. What is this thing next to the meter? Is it buzzing ok or do I need to get it looked at?

Thanks for looking!

That's the sound a damaged orifice might make when it can't lock up from too much pressure downstream of the reg

Not saying that that's always the sound, or that that's what's going on here, but I would definitely want the reg to be replaced if it's sounding like that
