A central
position
strengthens
double echoes
BA171Y73
A position away
from the filling
stream will avoid
interference
echoes
Echos from
fittings are
suppressed
during
calibraatrion
BA171Y74
A position above
the filling stream
will be subject to
interference
echoes
It is not possible
to measure in
tanks with
