Germ detector in pipes.

[Mykepatch]

I put a germ detector to head contaminated gasses to a special tank (in chlorine).

The detector is placed on a node pipe offering 2 directions, each one starting with a shutoff.

I configured detection to be active when more than 0 germ.

When active, detector opens one way and closes the other, and vice versa.

The problem is: sometimes, contaminated gas goes through the wrong way (not contaminated way).

Sometimes I see no germs in gas going through contaminated way... in this case, I could consider gas included 1 or 2 germs disappeared between moment they were detected and the moment I try to view contamination further in the pipe... but nothing is sure.

What is sure is that sometimes, contaminated gas is not detected.


Is there a known bug about that? I found nothing about it. Or does the dectector have to be placed in a special way?

You only need 1 shutoff. Having 2 does not help because the detected packet will have moved to one or the other. There is a tile at the white input tile where the packet will wait for it to open. It won't turn around to the open shutoff.

To make it work you first have to make sure neither way ever backs up. There are many ways to accomplish this that I won't go into. You place your sensor on the tile before the white input tile of the shutoff and have the 2nd option be to just pass through the tile. Like so: https://imgur.com/94C3n4m

Now if the valve is open the packet will go through. If it is closed the packet will pass by.

I occasionally have this problem with the sensors, but my solution is quite opposite from Hedning, so fair warning: I'm not trying to confuse you, just letting you know what is going on for me.

The sensors work great, HOWEVER, if there is a back up on any point, it can basically force other non desired packets to just stall or force their way the wrong way. so you can go Hedning's route, and make a system that never backs up, OR you can make a system that doesnt give a F about backups or problems.

Have a sensor right before 2 shut offs, with the pipe running through both inputs. Autowire sensor to first shutoff, and then to a NOT GATE, that leads to the 2nd shutoff.
Backups cant affect the system from the very end, since the pressured side wont move.
If there is a backup, it is because your destination is full, things stop. However I've yet to see any contamination with this, because flow stops if there is an issue, not continue on its way mixing up where everything is.

*(I'm currently using this to filter out gases into compression chambers, and will use germ sensors to create an instantaneous germ disintigration room for PW.)

PS: I love automation >.> Solves everything,

EDIT: changed some words to be more clear... If i'm still unclear let me know XD

Thank you both for your answers.

@Hedning
Actually, I tried your solution (I didn't realize that I could effectively suppress one shutoff... so stupid sometimes). I had no back ups but it seems to work well now. Strange.

@cainboy
Your description looks like my first construction..... but even with no back up, it had some issues.
I had build my system exactly like you describe yours. Or maybe I didn't quite understand.

Anyway it works fine now and thanks again to you both
