Pilot tube
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 pitot tube uses the relationship between velocity pressure, static pressure and total pressure to determine velocity… A pitot tube consists of two coaxial tubes. The centre one faces the airstream and receives the total pressure of the airstream, i.e. the static pressure plus the velocity pressure, while the outer tube has a ring of holes around the wall near to the tip and measures the static pressure only. Connecting the facing tube and the side tube tappings to the micromanometer will indicate velocity pressure directly.’
