gas flow sensing

[Craigjw]

I'd like to stop gas flow when pipes become backed up, my current way to do this is by splitting the pipe and placing an element sensor on one of the forks, then a filter, which deactivates a valve when the delay has been reached.

Is there a better or more efficient way to do this?

Depends on the type of gas and what you are using it for

[Saturnus]

You mean like this:

[Craigjw]

Thanks, that's what i'm looking for.  It's function is to just switch off the oxidizers or divert O2 to storage etc. when the air is at max pressure.

[Neotuck]

If you're just planning to divert a gas pipe when the gas is stopped up in a pipe then you don't need automation a simple gas bridge will work just fine

The same concept is used in infinite bathroom loops to prevent overflow

[Craigjw]

I also realised this, just after I also realised I had just built an infinite oxygen storage unit and was a little pointless, however, this technique would work for water flow also, which I need for switching off a sieve, as the current play through, I don't have infinite water storage.

do you know how to make one? they are easy to make with a little bit of oil

[Craigjw]

I think a sensor of this type would also work in conjunction with a mechanical filter, closing down the filter if there is a blockage and reopen after a delay.

I don't have oil yet, I made one with some water, it seems to work ok at the moment.... Until it fails!

Don't need oil at all.

You just build this anywhere that is not a complete vacuum and you have an infinite liquid storage. The gas(es) you build it in will be trapped inside and make sure the vent will never overpressurize.

Are the doors essential or can the same be done with walls?

walls will break

You can do the same with tiles, so long as you ensure that they are 3 tiles thick. 3-tile thickness will ensure zero pressure damage, regardless of pressure or material.

[Craigjw]

Metal or bunker tiles perhaps?

I haven't tried this but I'm wondering how you keep the gas pocket on the left?  If it moves to the right wouldn't that over pressurize the vent?

[Saturnus]

They break too from water pressure. Only doors or 3 tile thick walls will hold. Air flow technically also holds but you're relying on trapping gases inside here so those won't work in this particular set up.

All tiles will break eventually if 1-thickness or 2-thickness, even bunker tiles, though bunker tiles will hold up the longest.

Airflow tiles can technically hold infinite liquid pressure, but this is a minor exploit based on the 1-element-per-tile rule, since the airflow tiles contain gas. Airflow tiles and doors are the only structures that can hold infinite liquid pressure other than 3-tile-thickness walls.

It doesn't move. The air pocket will always be trapped over the vent no matter what.

You could have 2 gasses in there, and they'll occupy both top spots. Not hard to get 2 gasses if you drop some oxylite and bleach stone in before pumping in liquid.

[Ixenzo]

There must be two gasses for it to work reliably forever.

However, there is a preferred direction of travel when pushed from specific tiles.

[Neotuck]

I think I'll just stick with what I know on infinite storage like I have here for my petroleum and natural gas

[Craigjw]

That is a more compact version of what i'm using for gas storage, I will use this version in future.

I prefer the version that uses a reservoir inside the tank, it looks nicer imo.

Edit: I prefer this version also because it's super easy to spot what gas is in the box, and if for some reason you get the wrong gas in there it can sit above the CO2 or NG and still be fine.

[Neotuck]

Currently I'm working on a infinite filter system for storing all types of gasses I find outside my base, so far I'm up to CO2 and chlorine, soon I'll add polluted oxygen, oxygen, and hydrogen

[Nitroturtle]

Something like this?  (I know it's not compact, I like having plenty of room for piping)

I built this around cycle 150.  The NG one has 4200Kg per square lol.

Any time I see one of those infinite-storage schemes, I think about the ideal gas law and how long-overdue it is in ONI.
