Mass flow meter, compressed air
(OP)
is there an inexpensive thermal mass flow meter out there that has a range exceeding 2000 scfm.? I need one for 1 1/2" steel pipe. CDI Meters makes a nice inexpensive unit but it's flow range is only 2-200 scfm.

Thanks,

A vortex meter would probably be more accurate (1%), less expensive, cause less pressure drop, have wide rangeability, and still inherently linear in this application.

So go with the vortex and you cant go wrong. Rosemount is excellent but there are less expensive alternatives.
Let us know if oyu need more info
Good luck

The title of the thread indicates that the fluid is compressed air, although at unknown pressure and temperature. Coriolis is out of the frame from the 'inexpensive' requirement. They are many things, but cheap is not one of them! Vortex is likely to be as good a choice as any.
Rather than deciding what instrument you want to use, why not approach, say, Foxboro and Fisher-Rosemount and tell them what you want to measure, what your budget is, and what accuracy you need then let them spec the best instrument for the application? It sounds like you've already decided on the solution and are trying to find a way of implementing it, instead of deciding what performance you need from the instrument then finding an instrument to meet that requirement.

What are your temp and pressure specs?
To measure 2000 SCFM in our thermal mass meters, you need a 3 or 4" line size
