Just an idea what do you think? Obviously needs some condensers in there
IDK why it’s upside down lol

Hmmm I guess ik have to hook them up like that to see how it works out
I wonder if vapor locks might become an isseu but it s defenatly an option cool

Is your liquid line on top or bottom?
Right now I have them on top so a manifold of T s each with it a own ballvalve so I can independently interchange tanks if have to
And part of the butane condenses to liquid before entering the manifold and falls into the first tank in line overfilling that one first

I had kinda the same problem, i had each pump to it own condenser to its own tank and 1 would fill up a lil quicker than the rest. I just made it a lil less of a downhill ride for that tank and it pretty much evened them out.

Yes gravity is your friend so many solutions when using gravity instead of pumps
I think @Apothecary36 solution can work to if I would make somewhat short dip tubes on the overflow valves to have the overflow start at the 80% mark

Yes please do thx

I’d have to concur.
Why can u not manifold from pump and fill all containers at once? Best bet is 1000l storage container
If you need to go the multiple tank route, I would suggest using a large floor scale or possibly multiple floor scales.
This company, Scale Dynasty, makes the ones pictured above. Sizes start at 2’ X 2’ and go up to 7’ X 7’.
The 2’ and 3’ wide models weigh up to 5,000lb X 1lb.
Starting at 4’ wide they have the option for 10,000lb X 2lb capacity.
It says they include an under/over weigh alarm which sounds like it might be what you’re looking for.
I was thinking you could either do one scale per tank or possibly one large scale that all the tanks sit on and you re-tare once a tank is full.

He has sight glasses to see the volume of fill he has gauges to see the pressure he doesn’t need any damn scales lol

Well he specifically asked for scale recommendations so maybe he does.
I don’t think pressure would be a good indicator for tank fullness. It does rise a little as the headspace shrinks but it’s mostly tied to temperature of the liquid.

I figured out a few ways to tackle this beast. depending on budget and how many tanks. I’ll do a P&ID later if you go an electronic route.
If you have a npt port. Connect a level sensor switch to three way actuator gate valve. I suggest a T style not L. You want to run this in a series. Once it’s fills it will close your solvent path and head to the next one down.
My favorite if i was a baller. 5 way Acuator diverter valve and have this relay to a level sensor.
If you want a simple alarm look at this whole page
If you’re like na that to much electronics. Here is a simple mechanical floating ball valve that will close once it gets to your level. Don’t select this one find a 316. Suggest looking at fuel tank application.

Also if you want an automated system go with pneumatic instead. In refinery’s it’s mainly all pneumatic Bc of VOC leaks.

Yes i did sugest a scale that hit s an alarm once pre set weight was reached
Spoke to a gas supplier today
And they are very happy with the stop valve as long as tank is in a upright posision the work well
I think I am gooing for that route just. Want to find one with the float in one line not swinging sideway s thank you all
