Funny you should mention this. I just

in linear ft/min.

OK, thanks for all the replies. It appears I am in search of a Hot
Wire Anemometer. I've found several on the web, but all seem to use a
telescoping probe for measurement, probably for air ducts. Does anyone know
of a model that uses a wire for measurement so I can affix it to a modular
Multitude of instrumentation for this; mostly depends on if you need to
verify laminar flow, or just wanna know what the "blow-rate" is...
The most direct do-it-yourself instrument is to use the differential Vbe
between two transistors. Easy to do, and accurate. The T/C method is, in my

The type of airflow measuring kit you have mentioned is a Hot Wire Anemometer.
Starting price around $300. They will give you an air velocity reading in m/s or
ft per min. You will not get be able to get a true cubic ft per minute reading
using this type of device. For that you need a full bl
