Setup - Adjustment with the PC
• Click in the window " Meas. environment“ to
"Measuring conditions“.
• In the menu window " Measuring conditions“
you click on the options corresponding to
your application.
• Confirm with
"OK“.
After a few seconds of saving during which
the adjustments are permanently saved in
the sensor, you are again in the window
"
Meas. environment“.
Sonic velocity
When measuring in a gas composition devi-
ating from air, e.g. pure nitrogen, the sonic
velocity will change. Without correction, this
would distort the measuring result.
In the menu " Sonic velocity“ the sonic velocity
can be adapted to the correct value in case
of another gas composition.
• Confirm with "
OK“.
• Click in the menu window " Meas. environ-
ment“ to
"Quit“.
You are again in the menu window " Sensor
optimisation“.
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.
