The table shows the relationship between flow velocity V, flow quantity Q and sensor dimension size.
Guidelines for selection of sensor
Min. measuring range: 0-0.8 ft./sec. Max. measuring range: 0-33 ft./sec.
Normally the sensor is selected so that the nominal flow velocity is within the measuring range 1-15 ft./sec.
Flow velocity calculation formula:
GPM = (Pipe I.D. inches)
2
x velocity (ft./sec.) x 2.448
V =
GPM x 0.408
(Pipe I.D. inches)

or V =
(Pipe I.D. inches)
