Guide for sorting water by temp?

[Stretchytall]

Can someone point me to a guide for automating water sorting by temp? I created a system using pipe temp sensors and liquid valves. But for some reason, hot packets of water are sneaking in behind cold packets of water. It's like that cool valve isn't shutting fast enough. I don't know what I'm doing wrong. :(

Pictures?

Its an issue with last update valves(had same thing happen to co2 filtration)

Your issue would be because of at least a 1 piece of pipe length between the valve and the sensor (or I assume without pictures). I dont know of a guide to build something proper like this, which would then lead me to the question and statement of: Why do you need this? Regardless of why, fix the problem at the source. Not sass, just how I (and I assume a lot of people) fix issues.

What I mean is, instead of trying to figure out how to split them, see if you cant stop them from mixing in the first place. Would potentially cost less time, frustration and power. Cant really provide any additional suggestions without screenshots of what you are trying to accomplish.

EDIT - In theory, if the situation is temp change and distance traveled, a automation timer gate that would stop all paths for a few seconds should clear the pipes which may fix the problem. Again though, would need images to confirm.

Could also be caused by pipes backing up. Shutoffs as filters will only work reliably when there's no congestion.

Not exactly a guide, but this is how I'd do simple sorting build :

Only works if the ouptputs never back up, though.

I used NOT gates to allow only one gas to pass on each line (e.g. "if not O2 = green / open" - everything that is not O2 switches over to the next pipe.)
For temperature you could simply connect the sensor to the shutoff with progressively higher or lower temps .

Care to elaborate on that ? I've not been playing much ONI lately, but I feel like I should have noticed some issues with my system by now. That example I just built for the pic does work as expected.

This is an example that let hot water through the top pipe section. The two pipe temperature sensors are set to turn on when above 50 degrees C. The water in the tank is 75 degrees C. The flow rate of the hot water pipe is set to 2 kg per second.

The liquid pump is on, but the power to the two liquid shutoff devices are off, so the hot water loops around until the power to the shutoffs are turned on.

This example shows how to handle power out situation, and limited output pipe throughput.

Because the output pipe is limited, some hot water packets have to go through the loop a few times before being let out.

I just realized that another problem I had was the Insulated Pipe on the output cell of the rightmost Aquatuner keeps reporting periodical cold damage. I bet it's because packets of cold water are slipping through my valve arrangement and getting chilled below freezing temperature. So if you guys can help me figure out how to get the hot/cold packets to be sorted with 100% reliability, I'd appreciate it. I think that will solve both problems.

There has to be a way. I used to have a one-Aquatuner set up, and it worked perfectly. These problems only started when I installed the second Aquatuner.

I just had a "duh" moment while looking at another set up. In my above screenshots, aren't the two liquid shutoffs I have and each switching area redundant? Can't I just use one and send it the green signal when the water is the appropriate temperature, since liquid packets will always travel into the first 'input' they encounter?

[Nellvan]

Yup. That also eliminates what I'm pretty sure is the problem here : It's not the packet that's about to decide where to go that controls the shutoff, but the one behind it. The sensor needs to be right before the input.

[Nellvan]

Ok, I just found out pipe sensors can actually be placed on junctions, somehow I thought they'd only go onto simple straight pieces of pipe. So you could just move them one tile forward and it should work, even without removing anything.

In filters based on automation pipes needs to branch from shutoff input segment, not in place where sensor is.
