flow meter for "down draft webers"

[cak@dimebank.com (Chris Kantarjiev)]

If you have velocity stacks in your downdrafts, a Uni-Syn should work.
If not, you want the more expensive unit that has a calibrated
scale and a tapered inlet. Figure about $60; I bought mine from
Dave Bean Engineering a while back (see the monster list for
contact info).
