Accurate measurement and report of the performance allows ventilation equipment manufacturers and end users to make informed decisions about the equipment type and size for their facilities. The Bioenvironmental Engineering Structure and System (BESS) laboratory has been serving the agricultural ventilation equipment industry since 1990 by providing performance measurement collection and communication by publishing the performance data both in hard copies and online. The BESS Lab has a fan test chamber with a flow rate range between 47 L/s (100 cfm) to 18,878 L/s (40,000 cfm), at a pressure range of 0-2,000 Pa. The chamber was developed according to AMCA 210 for airflow measurement. This research aims to develop a new measurement and data acquisition (DAQ) system for the fan test chamber in the BESS Laboratory. This new system features updated electronic ambient air measurement systems, new temperature and pressure sensors, new tachometer and electrical meters, as well as an updated graphical user interface (GUI) that displays measured variables inside and outside of the chamber. The new system proved to be more accurate and robust, and user-friendly with more automated features, thus improving the performance of the testing facility. When comparing fan airflow tests between the new and old system, the airflow rates were found to be within -1.89% to 1.54% of each other.
