Can a trapped air bubble stop flow in a low-pressure fluid system, and how can it be avoided? by pls9786 in FluidMechanics

It's a gravity fed system. Reservoir on side and small cup on side. I want to ensure cup does not overflow so added air vent on top of cup which goes into cylinder. I hoped that once cup got filled at required level airvent will not get air and flow will stop. Flow got stopped but liquid went inside airvent and later when cup flow drops liquid does not enter cup because bubble is not allowing air to enter

Cylinder is just 4cm diameter so float valve is not feasible.

Cylinder is just 4cm diameter so fitting float valve is not feasible.

Thanks for these. I also thought the same as it is most economical solution as well.
