5. Enter the distance measured manually from the bottom of the
pipe to the flow surface in the Depth field or the range from
the pipe crown/sensor face (as applicable) to the flow surface in
the Range field. The measurement perspective depends on the
option selected in step 4. Enter any estimated deviation
corresponding to the measurement in the +/- field.
6. Enter the velocity of the flow measured manually using a
portable velocity meter in the Velocity field.
7. Enter the initials or designation for the field personnel in the
Crew field.
8. Enter any information corresponding to the field measurements,
the flow conditions, or location that may be relevant to the
confirmations in the Comments field.
9. Click on the Read button to prompt the monitor to take depth
and velocity measurements.
The Monitor Measurement section displays the depth and
velocity readings taken by the monitor.
10. Compare the manual field measurements to the sensor readings.
If a difference exists between the manual depth measurements
and the depth sensor measurements, you can compensate for
this difference by editing the electronic offset parameter for the
appropriate depth sensor. Consider applying this offset to
ensure the monitor produces the most accurate data. Use the
following equation to determine the electronic offset:
Field Depth = Sensor Depth + Electronic Offset
11. If the sensor reading is low, add a positive (+) electronic offset.
12. If the sensor reading is high, add a negative (-) electronic
offset.
Note: Exercise caution when applying an electronic
offset. Use an offset only when you are confident in the
accuracy and reliability of the manual measurements and
physical offset of the sensor.
