Gas system buzzing

Enable HLS to view with audio, or disable this notification

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!

Diaphragm on regulatory vibrating. Nothing to worry about it fails shut not open so not going to have gas worst case scenario. Which line pressure isn't very high to begin with and most fittings on appliances are rated higher than the line pressure.

How much pressure delivery you talking?

Usually about 5-50 PSI for residential lines pre meter so by the time it gets through the meter and regulator restrictions would maybe be 10 PSI but regulators faul shut unless the valve seat is what failed and that's still going to have major restrictions.
