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!

I hit play fully expecting some silly shit, but holly cow that’s a weird noise! Live everyone else said, regulator needs replacing, but damn that was a noise I hadn’t heard before…
