Point Velocity Measurement
Point Velocity Measurement in General mode is not bound to any measurement
techniques and or guidelines as required in Discharge mode. The location of the station,
number of point velocity measurements and depth of point velocity measurements is
dependent on the user requirements.
If the velocity measurements are used to perform hydraulic analyzes of the flow
conditions in a channel, either a laboratory or natural channel, it is recommended that
ISO 748 – 2007 guidelines are used.
Step 1
Station parameters defined for Velocity
Measurement, e.g., parameters of station defined for
velocity measurement are the following,
a) Location X: 1.534m,
b) Location Y: 2.978m,
c) Water Depth: 1,125m,
d) Measurement Depth: 0.6m,
e) Velocity Method: Two Point,
f) Comment.
g) To add station and continue velocity measurement,
i). Press the Right Soft Key.
h) To
CANCEL
a new station,
i). Press the Left Soft Key.
Step 2
Setting Measurement Depth screen allow the
setting and placement of the wading rod before
velocity measurement is started,
a) Wading rod setting,
b) Beam Check,
c) SNR,
d) Tilt,
e) Velocity angle.
f) To start a velocity measurement,
i). Press the Right Soft Key.
g) To
REVERT
to measurement screen,
i). Press the Left Soft Key.
The key features of the Setting Measurement Depth are explained in
