TozoM8 Posted February 12, 2014 Report Share Posted February 12, 2014 I have a new project that requires to measure airflow in a 14"x24" rectangle duct that is 15' long. It is part of a machine and sometimes they need to to turn down the fan. An airflow meter would ensure they turn the airspeed back to the same setting all the time. I will use a V130 to keep it low budget. Thanks in advance! Quote Link to comment Share on other sites More sharing options...

TozoM8 Posted February 14, 2014 Author Report Share Posted February 14, 2014 I was wondering if any of you ever used a cup or propeller type anemometer? The one I found is 5-15V DC. I guess they all setup to run on a car battery. Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted February 14, 2014 MVP 2022 Report Share Posted February 14, 2014 I wouldn't put an anemometer inside a duct. A pitot tube is typically used with a differential pressure sensor to report air velocity- http://www.dwyer-inst.com/Product/AirVelocity/PitotTubes/SeriesPAFS-1000 http://www.dwyer-inst.com/Product/Pressure/DifferentialPressure/Transmitters/Series668 If you're not familiar with these do a little Googling to learn how they work.

TozoM8 Posted February 16, 2014 Author Report Share Posted February 16, 2014 Thank you Joe! The reason I was looking at a cup or propeller type because this duct has a lot of dust in it that could build up on a sensor and give false or no reading.
