SAE technical paper on how mass air flow sensor/meter works
SAE technical paper on how mass air flow sensor/meter works Discusses voltage based and frequency based.
Has a lot of tables, charts, and formulas.

Interesting stuff, but a little deep for me once I got past the first 4-5 pages...

Yes, that is a great paper.
I still prefer the Laminar flow element with differential pressure sensor over the hot wire type.. but it'd be hard to put one of those in a car (err.. not cost effective..lol)
Making sure the system is calibrated properly is the key to accuracy with the MAF, any changes to the inlet of the sytem may have some net effect on the readings, especially when modifying the MAF itself
