The table shows the relationship between flow velocity v, flow quantity Q and sensor dimension DN.
Guidelines for selection of sensor
Min. measuring range: (0 ... 0.8 ft./sec)
Max. measuring range: (0 ... 33 ft./sec)
Normally the sensor size is selected so that the nominal flow velocity v lies within the measuring
range (1 ... 15 ft./sec.)
Flow velocity calculation formula:
1273.24 x Q [l/s]
V = [m/s] or
