Mounting and installation
¼ filling
When the vessel is empty, you see the ech-
oes of the vessel installations around the
emission cone. Beside the large bottom echo,
you see a number of additional false echoes.
The false echoes of the vessel installations
are saved during a false echo recording. For
this reason, the false echo recording must be
done in an empty vessel.
False echoes from the top down:
- first inlet tube fastening
- upper stirrer blade
- second inlet tube fastening
- angled inlet tube
- upper heating tubes
- lower stirrer blade
- remaining heating tubes
- vessel bottom
After filling, the bottom echo is replaced by
the product echo.
½ filling
Empty vessel
The product echo moves to the centre of the
meas. range. At the end of the meas. range,
you now see an echo at a position where the
bottom echo previously was in the empty
vessel. This echo is a multiple echo of the
product echo and is located at twice the
distance of the product echo.
