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, 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 validate it by clickin
g 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 to two other optimization operations and another filtered pparticularly efficient.
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 sensor.
-
If you can’t see that obliqu
e 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 does an 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.
