It does, but not as well as Plexi, probably due to the shallow 'cut' depth.
Went dark for quite some time.. personal stuff. When Honeywell shot down the safety valve thing, I took it badly.. lost both parents as a kid to gas explosion, let's just say I was heavily 'invested' (not money..soul) in making it happen. Techwise it is simple, a NC valve, pressure sensors before and after, and a gas sniffer interior to home. Microcontroller senses gas or pressure profile changes and NC valve releases, shutting off gas at meter. Could also of course communicate failure upstream, etc. Simple, saves lives, and never going to happen because retrofit costs would be on utilities, among other reasons. It's not the tech.
Anyway, now back out in Midwest where I grew up, tinkering, doing my thing.. a wiser if not slightly more cynical guy...
