Needle valve and bubble counter is a 2 in one item?

[octopus]

Is the needle valve and bubble counter a 2 in one item or do they need to be purchased separately. And basing on the video that i have seen the bubble counter is mounted on the regulator but reading other articles it seems to be refering to something else submerged in the water. I am confused

Its a separate item. I personally prefer the one that need to be conected via hose.

Submerge in the water? That probably diffuser.

Wouldnt it be unsightly to have another hose dangling around. Nevertheless i believe there is a reason for your preference. Care to share?.

Because it saver that way, i can add couple of check valve between regulator and bubble counter. Imagine if the build in check valve in the bubble counter broke, water will just go in to your co2 tank. Also, i am using inline diffuser, the whole co2 setup is hidden inside cabinet.
