Sharing a low volt conduit with non electrical tubing

I am wondering what the code would be, if there is one, for this situation. I have a low volt sensor wire, two conductor, that is part of an "autofill" system on a swimming pool. It runs in a conduit between the pool and the mechanical room. I would like to run two small vent tubes through the same conduit to vent fumes from the acid and chlorine tanks. There will be no liquid and no pressure in either tube..... Can I do this? Is there a code I can reference when I have the inevitable conversation with an inspector.

I see no problem with it and the NEC doesn't even address it. You have CL2 wiring that doesn't require conduit so running it in conduit constitutes a sleeve for it. Then you want to run some tubing along with it. This would be the same as running the LV wiring and the tubing together without the conduit. So unless there are some circumstances that you aren't telling us like the sensor isn't CL2 or the conduit terminating in line voltage enclosures, I see no problem.

No high voltage....my only problem is an electrician that is having a cow over the mere suggestion of such blasphemy.

No, not even in the definitions. It's only mentioned in the context of one way to protect cables where necessary. So basically for what you are doing there is nothing that addresses it so the code doesn't apply.

I disagree, how are you getting around 300.8
