What an eye-opener! I have 2 of these parts together and it didn't occur to me that together, they could be useful too. Thanks for the link and the pics of the diy parts. Hope more members could benefit from your experience. Thanks!
This is an excellant idea originally from APC posted by John N :
http://www.aquaticplantcentral.com/f...s-recipes.html
Adopted here with slight modification and using parts from local sources :
(1) Get a 5ml syringe from Guardian Pharmacy (cost S$0.30) and a typical checkvalce from LFS (~$2) :
(2) Use a pen knife to cut the rim off the syringe tube (do it with care) :
(3) Fill the syringe tube with water to half the level, and plug in the check valve.
(4) Connect the assembly. (CO2 bottle->this bubble-counter/check valve assembly -> diffuser (or reactor) at the tank.
Compare this ~$2.3 gadget with a commercial bubble counter (~S$5) and a check valve (~$2) - total S$7.
this is perfect for small size tank with DOY CO2 system !
(Disclamer : have not tested with pressurized CO2 system yet.)

If you've learnt, teach, if you have, give.
Don't walk behind me as I might not lead, don't walk in front of me as I might not follow. Walk beside me, as my friend.

Looks like a good idea. Would be great if can be tested on pressurised CO2. I never thought the rubber tubing can fit the syringe.
But some thoughts:
- the check-valve will still function if wet? I had experience once or twice the check-valves which let water flow back when wet.
- for DIY CO2, most folks have a 2nd bottle of water to filter the CO2 before passing on to the tank. See http://www.thekrib.com/Plants/CO2/co2-faiz.html for example. This 2nd bottle acts as a bubble counter too.

Would say a very innovative idea, may be neater this way compare to bubble counter.
