Measuring Intake Airflow
I have been looking at my options for continually measuring the airflow of my fresh air intake duct and haven’t found many methods that work with a fixed probe, most involve a probe traverse which is more suitable for spot testing but not really practical for ongoing monitoring.
An Averaging Flow Sensor probe looks like it could potentially work, but as I understand it they actually likely need their installation calibrated.
Is there any other type of probe that would be more suited to this type of use?
FWIW the intake is 6in round rigid duct and the sensor I would be using is a
Sensorion 816 Series
