- This advanced mode also allows to create “obstacle filter” that consist in masking obstacles echoes that disrupt the
measure like in the case of invert channel or ladder
rungs present in the field of view of the sensor.
After clicking on “Create an obstacle filter”, you need to choose with the tick box the obstacle matching the wanted
measure (water height), press “Create”.
- Once the filter has been made and checked, you need to confirm it by clicking the button “Launch a new measure”,
then adjust either the H or the H2 to ensure the quality of water height measurements.
Finally, this advanced mode allows two other particularly efficient optimization and filtering operations.
One computation parameter often named “oblique filter” works as follow:
- Choose a Filter y-axis of 160
- Adjust the filter slope until it becomes parallel to the power indicator (yellow line) and ends to the zero of the sensors.
- If you can’t see that oblique filter, adjust the y-axis.
The integrations count option, available for minimum, average and maximum, is the successive
ultrasonic shoots
treatment (3 by default). The average option calculates the average of those shoots. Most of the time the maximum
option is to be chosen to get reliable measurements (and especially in presence of condensation) but also depends of
the power setting of the sensor.
