Thermal 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: ‘A thermal anemometer (also known as a hot-wire anemometer) has a thin wire sensing element, which is heated electrically. When the element is exposed to the airstream, the electrical current or voltage needed to maintain the element at a constant temperature is measured and calibrated to give the velocity of the air.’
