Set-up

Adjustment with the PC on VEGAMET

In the following figure you see the echo curve
before correction of the installation angle
(directing to the product surface) with a false
echo which has nearly the same size than the
product echo and which is caused by a strut.

In the next figure you see the echo curve
after optimum directing of the sensor to the
product surface (sensor axis vertically to the
product surface).

You see that the false echo caused by the
strut is here reduced by approx. 20 dB
against the useful echo and hence can no
more influence the measurement.

• Quit the menu window

"Echo curve" with

Quit".

With the menu point "

False echo storage" in

the menu window "

Sensor optimisation" you

can cause the sensor to mark false echoes.
The sensor electronics then saves the false
echoes in an internal database and treats the

false echoes at a poorer degree than the
useful echo.

• Click in the menu window "
