3. Project guidance
The table shows the relationship between flow velocity V, flow quantity Q and sensor dimension
DN.
Guidelines for selection of sensor
Min. measuring range: 0-0.25 m/s
Max. measuring range: 0-10 m/s
Normally the sensor is selected so that V lies within the measuring range 1-2 m/s.
Flow velocity calculation formula:
1273.24 x Q [l/s]
V =
