Air Flow Meter for Homeowner

[cem-bsee]

so, after you measure this, what are you going to do?

why not just do that? work on the solution, not just measuring how much problem --

eg: seal all the ducts & cracks with mastic
have dampers in the duct take-offs from the trunks
adjust dampers until all rooms are +/- 3F just after blower shuts down

it takes some patience to set dampers --
& may need different settings for summer & winter

I prefer and have used the
Extech 407114 Heavy Duty CFM Vane Anemometer
which has a 2 3/4" Diameter vane.

TWO people would be needed if you used a 'home-made flow hood'.

I believe that the larger vane would provide a more accurate reading with 'inherent averaging' due to a larger 'sampling area'.

Therefore, a 'home-made flow hood' would not be a necessity in making an initial total air flow assessment.
