The tables show the relationship between 󹪞ow velocity v, 󹪞ow quantity Q and sensor
dimension DN.
Guidelines for selection of sensor
Min. measuring range: 0 to 0.25 m/s (0 to 0.8 ft/s)
Max. measuring range: 0 to 10 m/s (0 to ft/s)
Normally the sensor size is selected so that the nominal 󹪞ow velocity v lies within the
measuring range 1 to 3 m/s (1 to 15 ft/s).
