CASE 1 :

Ideal case

: unique echo (test in lab or if the sensor front flat water surface for example)

A simple calibration would be possible.

CASE 2 : Case of a classic man hole with at the bottom an invert. The figure bellow shows two echoes (the
invert and the water). A calibration in advanced mode will be possible. First check that the sensor is

well

positioned,

fronting and

perpendicular

to the water.
