difference in bubble count
i have pressurized co2 system and use co2 grade tubing from the regulator to the bubble counter. I use silicone tubing from the bubble counter to the glass diffuser. I noticed that there is a difference in the number of bubbles I counted. The bubble counter shows 113 bpm, while the end of the silicone tubing has around 46bpm. Does this sound normal? I know that bubble size can effect the count, but i cant really tell the difference in sizes.
