Rotating vane anemometer
Commissioning Air Systems (BG 49/2015), written by Chris Parsloe and published by BSRIA in March 2015, explains how to commission ducted air distribution systems in buildings. It was originally published in 2013 and was then updated in 2015.
It states: ‘The main application of the rotating vane anemometer is the measurement of flow rate at grilles, hoods and other relatively large openings. Mini rotating vane anemometers have a miniaturised measuring head, making them suitable for smaller openings such as slot diffusers. Examples of vane anemometers are shown in Figures 10 and 11. Vane anemometers give either a direct reading or average the readings over a few seconds and display the final result. The typical operating range of a vane anemometer is 0.25 to 30 m/s in the air velocity mode, or 4 to 70 l/s when fitted into a flow capture hood assembly.’
