I have answered questions similar to this a few times recently. You can do a search in the top right-hand corner of the forum to find existing topics with the answers.
e.g.
The best way if you don’t have a refractometer is to go by cappings. If it isn’t fully capped, please just spend the $40 on a refractometer - it costs a lot less than a Flow super.
Late morning, but give yourself at least 4 hours to get every last drop.
Open in 20% sections, leave 5-20 minutes between sections and never let the Flow tube get full to the top. Most of the time the problem is an airlock in the Flow tube.
Please have a search through the forum for answers, and if you can’t find anything after a bit of looking, we’ll do our best to help
