fluid priority
The Alumina Scrap refinery produces water at 120g/m and the Alumina Slurry refinery consumes water at 180g/m so I connected the two. There's not enough water so I added a water pump.
Now, the Alumina Scrap barely runs because it is full of water. How can I tell the Alumina Slurry refinery to FIRST use water from the Alumina Scrap refinery so that it can run? Only use water from the pump when needed

Why not overclock/underclock and balance the numbers?

Oh, and to answer your question directly, I don't think there's any easy way to "prioritize" fluids like that.

Hmm okay, I've got the power shards for it.

I thought there might be a way to prioritize with like a tank higher than all of it, or halfway between. I suppose I could experiment with that myself, but I can't quite understand fluid dynamics. I have a tank that won't fill. It's uphill. I thought it would fill to the top, but last, but it seems it will never fill more than a certain line in the tank? The supplying refinery is full of output fluid. I thought the tank would fill to the top ONLY when the refinery was forcing out enough pressure to force it uphill. Is it your understanding that tanks uphill with never fill to the top, they only fill to the height of the supplying machine +10 m.

How high is 10m in this game? The height of a Constructor?
To me it looks as though the tank is 3m above the refinery. That's why it will only fill to 2/3?

Use a pump to pump up water at higher level height then use a tube (with valve) that goes straight down to merge with main tube of refineries

A production building has 10m deadlift by default. If a fluid buffer is raised such that only the bottom 4m of it is within that range, then only 50% is able to fill (the top half is outside the deadlift range).

In the game, how tall is 10m?

Foundations and Walls have dimensions. Use them to determine the scale in game

I put in a valve. Water pump is lowest because that's where the water is, I don't know why you say it should be highest. I set valve to 60. Oddly, set to 60, the flow is 59.1
This is when I set valve to 60.0 60.1 and 60.2
When I set valve to 60.3, it flows at 61.4
This does not make sense and is broken. What am I doing incorrectly or are valves buggy?
Refinery does not have enough water, and I don't want to supply more than 60.0 or the refinery will eventually stop.

ah good okay thanks.

The simplest answer is that gravity creates fluid priority. There's other, more complicated and less reliable methods, but gravity always just works. If a fluid is feeding a pipe intersection from above, and another at lower level, the one from above will be prioritised.

Flow rate limiting is best reserved for very rare scenarios. It is very rare you want a continuous feed less than the pipe can handle, as machines are not continuously fed - they take a gulp, then operate until the cycle's ended, then take another gulp (nor do they continuously output fluid]. By limiting flow, more often than not you'll end up creating slushing and enhancing your woes.

Generally with fluids, you want full pipes going into machines [to ensure continuous supply], and empty pipes coming out [to ensure they can also dump an output when needed].

Valves tend to be more useful simply to stop backflow and/or cut headlift.

You can definitely use limiting to solve your current challenge, but it calls for a more elaborate method involving buffers, than just basic gravity.

You can extrude a beam in increments of 1m.

Domyou.need a screen shot of how.to.place.a.quick.and dirty fix for priority fluids?

It just need a foundation, two pipes, a pump, a valve and a small fluid container

Placed at middle of a pipe..
Not only does what you need, but even guarantee that it can keep empty the output even if for some reason (for a brief period) the consumer isn't consuming any fluid at all)

I had the same kind of setup. I fed from the pump to a tank, then pulled from the tank into the rest of the system across a valve.

Yeah...the valve took some jiggering to get just right.

But the fiddling with limiting isn't necessary if the water extractors're clocked to output the required amount and the water from the refineries is prioritied with gravity.
