Surface Velocity
Accuracy +/- 0.25 feet per second (0.08 m/s) or 5% of the
actual reading (whichever is greater) in flow
velocities from 1.00 to 15.00 ft/sec (0.30 to 4.57
m/s)
Note: Flow conditions may cause the designated
accuracy to vary and hinder or prevent the
effective use of surface velocity technology.
