CASE 3 : Complex case
The presence of many echoes make difficult the calibration the easiest way. A priority should be to move the
sensor if possible otherwise go to the expert mode. (Only for experienced users).
Calibration of the sensor Case N°1 (Ideal)
The first case presenting only one echo, you only need to adjust the water height H or the maximal distance
between the sensor and the bottom
Z and relaunch a measure. Note that it is possible to define a different zero
point (zero at the level of an overflow threshold for example), very useful for CSO (Combined Sewer Overflow).
Zero of the sensor (example of ideal case) – On the right a different zero point
Once done, the calibration has to be validated by clicking on “Apply” button. The configuration is then
automatically saved in a file called “configuration” that is visible with the software even when not connected to
the sensor. Please note that the figure presenting the echo as a power indicator, showing by a yellow dot line
(oblique from left to right). This one is very useful to fine tune the sensor. The echo should ideally be upward
that line. A weak echo means measurement not precise, a too high echo provides accurate measures but use
faster the energy. A temperature checking during the measure has also to be done (23°C in this example). While
the measure is temperature compensated, you should not calibrate a sensor when the temperature is too high
and then asking it to measure on a different environment (typical case of 15°C under a sewer manhole).
