Depending on the manufacturer, high velocity ducts leak no more than 5% of the air forced through them, if they leak at all. Many can have a 0% leakage if they are installed professionally and ...

The InnovairFlex™ duct smoke detector line offers a variety of detectors ... and a readily accessible test feature. The detectors have an air velocity rating from 100-4,000 feet per minute (0.5-20.32 ...

Air velocity is measured in a grid pattern through a variety of openings. They typically include ducts, registers, grilles, filters, economizers, and grease filters. For the purpose of this article, ...

Measuring air ... a duct. It’s another one of those “Why didn’t I think of that?” things that makes perfect sense in theory, but takes some engineering to turn into a functional sensor.

The PAV3000, unlike thermistor-based solutions, has a MEMS sensor core that is minimally affected by ambient temperature changes and which provides instant real-time feedback on proper air flow at ...

The FMA900A features a hot wire air velocity sensor design, 2% full scale accuracy, two sensor probe configurations: fixed mount and remote probe, a 250 msec response time, 0-5 Vdc or 4-20 mA analog ...

When we hear the words “pitot tube,” we tend to think more of airplanes than of air ... duct flow meter, we’ve covered one before. We’ve even seen a teardown of a pitot tube sensor system ...
