I am starting to appreciate how important the gas sorter thingy is (like the one you started pretty early on the left) - without it it is hard to fill exosuits (without a way to reliably divert non-O2 gas), run an oil refinery or polymer press. I've been having a heck of a time making it though -- I need to find a way to reliably put less than 1.5 kilos of water on the vent, and often when I drip small amounts (30 g using the tile runoff method you showed me) the water gets displaced or just disappears. What is your secret?
First it's better to use oil instead of water, you can deal with more extreme tempatures without having to worry about boiling or freezing.
Second you need one full tile under the vent. This prevents liquid deletion that sometimes happens when gas passes though the vent.
Third the hydro sensor is just to give player control over the pumps, turning them on/off whenever you need them. You can also use atmosphere or thermal if you prefer.
