Unknown equipment at meter station

[LuckyCharms]

I found a covered device while looking through some photos and I'm having a difficult time pinpointing what exactly it is. There appears to be a handle and potentially a bleed port. Based off location, a blowdown would make sense, but I've never seen this sort of equipment for that process. Any guidance would be much appreciated.

The weather covers suggest electronics inside, as in transmitters, but I couldn't see any electrical connections, and that doesn't explain the handle.

Maybe battery powered recorders with a big quick-release handle, that are detached and carried away for data transfer and battery charging?

I wouldn't be measuring anything at those locations, even less recording it on a data logger. It's not an appropriate location for anything more than blow down. I think it might be a relief valve with some kind of testing device attached.

It looks like a lift lever on an Open Yoke PRV. A lifting mechanism is used to test for correct valve operation at all times where corrosion, caking, or any deposit could prevent the opening operation. Foreign particles can lodge under the seat of the valve when it discharges. The lifting lever allows you to lift the valve and flush the obstruction.

"It looks like a lift lever on an Open Yoke PRV." Except here there is no Outlet Nozzle.
We need someone to get a photo of one of these with the "Bag" removed.

Sometimes its possible to do all the right things and still get bad results

Would be no mystery and take the fun out of the discussion if the bag was removed.

Yes, it is a pig in the poke until someone removes the bag.

It's a metering station. Could it be a gas sample point to take samples for gas commodities testing??

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I thought you meant testing of the relief valve.

BigInch:
“I don't know her....” and ‘put a bag over her head,’ in the same discussion? MikeH used another phrase, “ weather covers,” but I never heard that phrase used that way before. Is this pipeline guy talk or what?

 

[BigInch]

You were the one that said "‘put a bag over her head".
I have no idea to what you're referring to there.

Maybe a new game for engineers? Cover things with bags, take photographs and then let people guess whats inside the bag?

Engineering twist on Airport Security Melborne. Good one.

Whatever is under that bag must be "Coyote Ugly"!

MortonA, that's really funny.

Pilot operated RV combination with solenoid valve triggered blowdown valve?
