In order to evaluate and/or control its performance, an accurate measurement of the velocity and temperature of the air passing through the duct is needed. Normal commercial equipment, developed for other applications, does not suit this particular scenario very well. An ultrasonic velocity meter has been specially designed, manufactured and tested inside an actual chimney, proving that this approach is a reliable solution to the problem of measuring the ventilation parameters. Here a detailed description of the instrument is given, along with a presentation of its first operational tests.
