New to this forum, first post. I did use the search function first, but found no relevant info that would answer my question.
I'm right around 200 hours, so I figured I should give the circuit network a try

My second idea I think I may have bitten off more than I could chew. I have an inserter that pulls flamethrower fuel from the assembler into a steel chest to the right, then another inserter that pulls into a passive provider chest to the right of that. I want the second inserter to only enable once the steel chest contents have reached >100 and stay on until the steel chest's contents reach 0. Repeat.
Basically, I only want the 2nd inserter to move 100 units of flamethrower fuel at a time.
Any clue or help would be greatly appreciated!
