Not sure if this is possible but...
I was wondering if there was a way to set something up so that one liquid would siphon into a lower container and stop when the liquid reached the level of the tube opening without using any sort of valve???
Basically I need a large volume of liquid to feed into a small volume bottle then shut off when the smaller bottle gets to a certain level. I think there may be a way to do it using either or both the siphoning effect and capillary effect.
The main point is to minimise (actually eliminate) moving parts like valves.
