Active on level measurement via water-ultrasonic from the bottom and air-
ultrasonic from the top.

Fig. 9-135 Display echo profile with sensor type POA/OCL
This graphic enables the service personnel to assess the quality of the echo sig-
nal in the measured acoustic path. Ideally the first peak (reflections from the in-
terface between water and air) is very narrow, steep and high, all further peaks
(double and multiple reflections caused by the echo signal moving back and
forth between the interfaces water/air and water/ground) are lower and wider.
