Measuring Mass Airflow with the Wind Sensor?

[fahrvergnuugen]

I've been searching for an economical way to measure and datalog mass airflow. If the Wind Sensor were to be installed in a 2" PVC pipe, wouldn't it be possible to calculate the amount of air flowing through it based on the speed and temperature?

Absolutely. Wind speed times area = volume / time. You'll need to compensate for temp using gas laws, also humidity comes into play depending on how accurate you are planning to be.
