I looked at the specs. on the MW-1 and while it could be handy for measuring air VELOCITY....and you could use a calculator along with it to arrive at air FLOW......it would be a royal PITA to do it that way.
What you probably would prefer is a model that will let you put in the duct size your are measuring the flow on and have the device calculate CFM.
I don't think that device, judging from the specs. will do that.
IMHO you may want to look for a different model that would be more advantageous to own.
I have a Mannix anemometer that will calculate ductflow in CFM.
It measures the temp. of the air as it measures the velocity and volume.
It's on the low end of the 'economic spectrum', LOL. But it works for me.
Dwyer makes some other models that are better targeted at the HVAC service industry.
For just a few bucks more you can get one with the better 'features'.
BTW, with most of these air flow/speed instruments you'll need to make several measurements and average them OR be sure to make a drawing or picture of where you placed the 'pickup' or it's orientation when you made your measurements.
Otherwise, repeatability will suffer and your data will be inaccurate.
Good luck with you air measuring!
