The different methods for air flow rate measurement at air terminal devices are presented in this overview, such as van anemometer with a cone, small velocity probe (thermal probe or small vane anemometer), compensation method, etc. Several measurement methods are available on the market at highly variable cost. However some of these methods are suspected to lack reliability.  
Some of these measurements methods are not really appropriate for the measurement of flow rates at air terminal devices, with errors up to more than 50% in some cases! This overview paper aims at identifying the main problems of measurement at ATD and possible solutions to overcome these problems. This is based on the lab measurement tests and on site measurement campaigns carried by different research team the last years: BBRI in Belgium, BSRI in the UK, Cetiat in France and LBNL in the USA.
