what is this beta ratio?

I recently read a "report" from Daniel indicating that required

diameters are now 44D and other increases in distances are required for
thermowells within the flow. There was also some mention of new
permissible orientation of flange taps and distance to transmitter.
The solution seemed to be flow conditioners.
Yes, I already know that upstream requirements depend on beta ratio as well as piping configuration.
Can anyone shed some light on this?
Off onto a slight tangent (but still related to flow measurement), I'm not too experienced with orifice fittings and once had "someone in the know" tell me that these devices were transmitters in themselves and required less up and downstream straight-run requirements. Umm, OK. How does this misinformation become a meme; by people misunderstanding and propagating wrong info because it makes them feel informed? People not bothering to look stuff up on the internet for 30 seconds?
The odd thing I found was that people thought the device was some kind of magical box that had special properties.
