Ken,

Measuring the hot wire resistance isn't that big a deal. The trick will be
to factor the incoming air temperature into the equation because this
affects cooling. You will be driving an output resistance with the results
of two curves, the hot wire resistance modified by the incoming air
temperature.

Should be an interesting project.

Thanks,

Subject: Re: AIR FLOW METER

   I am working on one. I have gotten as far as finding a Nissan MAF that
is an exact physical replacement for our AFM and is plentiful in
salvage yards. It bolts up perfectly to the 2.1L air cleaner box and
fits the large hose. I have done some preliminary electrical
measurements and things look promising.
    I have so many pokers in the fire I keep getting side tracked . such
as  my  DIY synth : http://www.musicfromouterspace.com/
stay tuned......
