I no echo is found within the defined tank height (Tank/silo height parameter
4)
), the
tank bottom searches beyond this distance in the Tank bottom range to see whether an
echo from the tank bottom exists.
If a tank bottom echo has been found, a level of 0% is assumed. If neither a direct level
echo nor a tank bottom echo has been found, an echo loss is reported (error message
S941).
• Level echoes from within the measruing range always have a higher priority than
the tank bottom echo.
• The first echo factor is not applied to the tank bottom echo.
