Issues w/bubble count

[lilchris_357]

Good Day, I'm having issues getting a steady bubble count through my reactor. My reactor is controlled by APEX. When the valve on the reactor is opened the CO2 comes out in an inconsistent rate. I will get 2 bubbles then 1 bubble, then nothing for about 5 secs, then 2 bubbles, 1 bubble, 2 bubbles etc. My question is how should the bubble come through the reactor should it be 1 bubble at a time? Have you seen 2+ bubbles come through the bubble counter?
