How to fit oxygen flow meter to welding tank

[roflbrew]

I have this O2 welding tank from Harbor Freight - it has a CGA 540 male outlet valve:

And I have a Precision Medical oxygen flow meter - I think it has a 1/8 NPT female inlet.

Is there an adapter or something else I can buy to get these two things to work together?

Thanks!

You need to put a regulator on the tank and run tubing from the regulator to the flow meter.

That will work - I was clearly over-thinking it. Thanks for the perspective!
