You ARE psyching yourself out, lol.
REad the middle of the flow ball.
CO2 is an art; if your flow is slightly higher or lower you are not going to have a problem because of that, don't fret.

The only thing is that the flow ball is supposed to drop to the rest position when the solenoid clicks off at the end of 15 minutes. If you feel CO2 still releasing from your hose, you have a problem- bad timer or solenoid valve, or your plumbing is incorrect.
stinkyattic Reviewed by stinkyattic on . question about CO2 regulators How exactly should you read the flow meter? Top of the ball, middle or bottom? Also, does it make sense that the flow seem present even when the switch is off? I'm just trying to ensure I don't have some kind of leak. Even when unplugged, the flow "ball" floats. Right now I have the ball in the middle of the 1. 224 sq ft area. I run the tank for approx 15 minutes, then wait another 30 minutes before kicking in the blower. thanks Rating: 5
