Explanation: From your context "compressed gas tanks and containers", I conclude that this might relate to above-grade/overground tanks/containers (Oberflurbehälter or Überflurbehälter) vs. underground/subsurface tanks/containers (Unterflurbehälter).
The "fluor" (fluorine) bit is almost certainly a typo for "flur".
Judging from the context, and given that there are indeed other typos in this text, I'm inclined to agree that this is probably what they meant. The text is about propane, and filling tanks for homeowners and businesses, not flourine, so I certainly agree that flourine is not what is meant here, as what use would a homeowner have for flourine? And underground propane tanks does generate google hits. 4 KudoZ points were awarded for this answer
Could you give some mroe context? I'm wondering why there isn't a single valid google hit for Fluorbehälter....

Oberfluorbehälter
overflow container
Explanation: Funny word in German: 'oberfluor-' sounds like 'overflow'. I am only offering an alternative to your own suggestion 'top-discharge container'

Explanation: I would guess that this is about the placement of tanks; if they are placed above X, they are called top..., if they are below X, they are called bottom ...
Any more context?

Asker: No, unfortunately I don't have more context, and I couldn't find a single google hit on these terms either.
