Question

How do I hook up my Magnehelic® gage for an air velocity application with a pitot tube?

Answer

In our Application Guides on flow products, 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.

Question

Trying to measure differential pressure between OSA and indoors. Using transmitters with a range of +25pa to -25pa. Monitoring pressure variations occur from basically 0pa to 20pa over a short period of time (15 to 30 sec) Building is basically closed during testing, suspect OSA fluctuating due to winds? eddy currents etc. Any ideas, Building under positive pressure is critical for safety reasons Any ideas?

Answer

Whenever you are using outside air for a static pressure reference, fluctuations in outside conditions can cause erratic differential pressure readings. By using one of our outdoor static reference probes, you can diminish the influence of outdoor weather on your reading.
