9. In the Station menu, select Edge/Obstruction. Select one of the options.
Option Description
Left Select this option if the station is at the left edge of the water or an obstruction (i.e, sandbar,
pylon or large boulder).
Right Use this option if the station is at the right edge of water or an obstruction (i.e., sandbar, pylon
or large boulder).
Open water Use this option to configure the edge as an open water environment (default).
10. Select Distance to Vertical and enter the information.
11. Select Set Depth and enter the information. If at an edge, the meter automatically sets this value
to 0.00.
a. If Manual mode was selected in the Profiler setup, enter the total depth of water at this vertical
position.
b. If Automatic mode was selected in the Profiler setup, push OK to set the maximum flow depth
at the value shown.
12. If Left or Right was selected in Step 9, enter an edge factor for the vertical. Select a factor from
the list or User-defined. For User-defined values, enter a roughness factor between 0.50 (very
rough) and 1.00 (smooth). The roughness factor is relevant only for right angled cross sections. It
is used as a factor in the calculation of the discharge proportion of edge areas. For example:
• Smooth edge with no vegetation (e.g., concrete, steel, cement)— 0.8 to 0.9
• Brick sides with vegetation— 0.7
• Rough walls with heavy vegetation—0.6 to 0.5
13. Select Measure Velocity. Select the number of points on the vertical to collect.
14. Select a measurement point from the list. Obey the instrument prompts and adjust the sensor to
the correct depth. If the sensor has a depth option, adjust the sensor depth until the depth box is
green. This means the sensor is in at the correct position.
Note: Red indicates more adjustment is necessary. Yellow indicates the depth is close to the correct depth.
15. Select Capture to start the measurement process.
16. If necessary, the setup can be changed and the measurement can be repeated. When the
measurement is complete, push OK to store the data.
17. Repeat steps 13–16 for the other measurement points on the vertical.
18. When all measurements for the station are complete, select Main or Verify. results. Push OK to
return to the list of measurement points.
Option Description
Main Returns to the station menu.
Verify Shows the average velocity reading for the station based on the measurement method.
19. Select Next to go to the next station.
20. Repeat steps 10–19 for the remaining stations.
21. When all measurements for all stations in the profile are complete, select Channel Summary to
view the results.
Note: A warning flag will show if the discharge in one or more segments is > 5% of the total discharge.
Insert or delete a station
Prev, Next, Ins and Del options show at the bottom of the display in the Station screen. Prev and
Next are used to navigate to a previous or subsequent station. Ins and Del are used to insert or
delete a station.
For example, after measurements have been done at 10 stations, a user may wish to insert a new
station between stations 3 and 4. The steps below describe how to do this. These steps can be
applied in similar situations.
