Mounting and installation
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
¼ filling
After filling, the bottom echo is replaced by
the product echo.
½ filling
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.
Filled vessel
When the vessel is completely filled, you see
additional multiple echoes at two, three or
four times the distance of the product surface
echo.
