How do I hook up my Magnehelic® gage for an air velocity application with a pitot tube?
A. In our online primer on flow products work, we explain very well how to take air velocity readings. The total pressure connection on the pitot tube is connected to one of the high pressure ports on the gage. The other high pressure port is plugged. The static pressure connection on the pitot tube is connected to one of the low pressure ports on the gage. The other low pressure port is plugged.
