A device for in-situ fan airflow measurement, called the Fan Assessment NumerationSystem (FANS) device, previously developed and constructed at the USDA-ARS SouthernPoultry Research Laboratory, was refined at University of Kentucky as part of a project forquantifying building emissions from poultry and livestock operations. The FANS incorporates anarray of five propeller anemometers to perform a real-time traverse of the air flow entering fansof up to 137 cm (54 in) diameter. Details of the updated design, including hardware, software,and calibration methodology are presented. An error analysis of the flow rate, and calibrationresults from ten units recently manufactured, is provided. Sufficient details of fabrication andcalibration are presented so that interested readers can replicate a FANS for their use. Fulldesign details are provided at www.bae.uky.edu/IFAFS/FANS.
