2.1.3

Operating principle

FLOWSIC60 operates by measuring the transit time difference of ultrasonic pulses. The
sensors are mounted on both sides of the tunnel at a certain angle to the flow direction
(

Fig. 1

).

The sensors alternately send ultrasonic pulses to each other. Depending on the installation
angle 

α

 and the air velocity v, the transit time of the respective sound direction varies as a

result of certain "acceleration and braking effects" (formulas 2.1 and 2.2). The transit time
difference of the sound pulses traveling from  sensor  A  to  B  and in  opposite  direction  is
directly related to the air velocity. The air velocity v is calculated from the transit time
difference of the ultrasonic pulses, independent of the velocity of sound. Changes in the
velocity of sound caused by pressure or temperature fluctuations, therefore, do not affect
the calculated air velocity with this method of measurement.
