RE: How do you measure system airflow?
So much of what we do requires either measuring or approximating airflow measurement on the entire system (over the evaporator coil) what method or methods do you use?
If you absolutely had to get a system air measurement within 5% of reality on every call what method would you use?
@Bryan not enough points to comment yet, but I do a timed traverse method, I have the quick reference sheet from trutechtools that has the position of the holes to drill based on duct dimensions. Feel free to delete this since I can’t reply to your comment on my post, I did update the post to say that I use a timed-average traverse.
