My Hobart BetaMig 250, bought in the 90"s, uses a flowmeter, and I also run 20-25 CFH.
My neighbor just bought a new Miller 225 from the same welding supplier, and is does NOT have a flowmeter, just a low pressure gauge. I haven"t had a chance to look at the operator"s manual to see how the correlate the PSI readings to flow.

Miller 252? You have a flow gauge instead of a flow meter. The gauge will still read in CFH the same as a flow meter. 30 CFH is about the norm for MIG. A lot of times the parameters for the wire will list the recommended gas flow as well.
