Someone gave me an interesting article:

   An Inexpensive Sonic Anemometer for Eddy Correlation
   by G. S. Campbell and M.H. Unsworth
   _Journal of Applied Meteorology_ v. 18, August 1979.

It uses inexpensive ultrasonic transducers and PLL circuitry.  It has 
no moving parts, detects very low velocities, is directional, low-
powered, and can be built from about $20 worth of Radio Sh*ck parts. 
It also has a temperature output.  I plan to build one for cave-wind 
and other infrasonic studies.  Copy for SASE.
