Guidelines for selection of sensor
Normally the sensor is selected so that V lies within the measuring range 1 to 2 m/s (3 to 7 ft/
sec.).
● Min. measuring range: 0 to 0.25 m/s (0 to 0.8 ft/sec.)
● Max. measuring range: 0 to 10 m/s (0 to 33 ft/sec.)
Flow velocity calculation formula
● Metric measures:
V = 1273.24 x Q / Di
2 (
V: [m/s]; Q: [L/s]; Di: [mm])
or
V = 353.68 x Q / Di
2 (
V: [m/s]; Q: [m
3
/h]; Di: [mm])
● Imperial measures:
V = Q x 0.408 / (Pipe I.D.)
2 (
V: [ft/s]; Q: [GPM]; Pipe I.D.: [inch])
or
V = Q x 283.67 / (Pipe I.D.)
2 (
V: [ft/s]; Q: [MGD]; Pipe I.D.: [inch])
