Echo curve
If, due to vessel installations, you expect
strong false echoes, a correction (if possible)
of the mounting location and orientation (dur-
ing simultaneous monitoring of the echo
curve) can help localise the false echoes and
reduce their intensity. With the menu item
"
Echo curve“ in the menu window "Sensor
optimisation“ you can see the form and the
intensity of the detected ultrasonic echoes.
In the illustration, you see the echo curve
(before correction of the sensor orientation)
with a false echo nearly as large as the prod-
uct echo.
In the next illustration you then see the echo
curve after optimum directing of the sensor to
the product surface and away from a large
false echo source (sensor axis perpendicular
to the product surface). The false echo,
caused e.g. by a strut, is now reduced by
more than 10 dB and will no longer influence
the measurement.
• Quit the menu window " Echo curve“ with
"Quit“.
