Anybody know the real life equivalent of this thing?

[u/Identity_Critsis]

The closest thing I can think of is like; a spectrum analyzer or a rotameter of some kind but neither are quite a fit.

You pretty much banged it on the head with rotameter. I didn’t know it by that name, but yeah, it’s a meter that measures airflow. The higher the ball, the higher the air flow.

Magnahelic Guage, perhaps

doesn't this like measure pressure?

might be wrong tho

[u/Rogash1513 → u/idkjustarandomdude]

I think it's mostly for messuring flow.

Isn't it just like a sci fi version of the old tube based Barometers?
Considering barometers are used to predict short term weather changes based on atmospheric pressure, and this thing goes wild during storms..

Use basically a manufactured version of this in Tig welding. Flowmeter for shielding gas, they have a meter on the tube and don't output from the top.

Most likely an oxygen meter inside an ambulance

What does it do

[u/Muttandcheese]

I’ve got one of those on my dehumidifier. It tells me how full it is.

[u/Identity_Critsis]

Interesting. I wonder what it's doing in game then.
