The reference plane for the measuring range (version A) is the
lower edge of the flange. The reference plane for versions B, C
and D is the lower edge of the transducer.
Make sure that for all versions a min. distance - the so called
dead zone - below the reference plane is maintained in which a
measurement is not possible. The exact value of the dead
zone is stated in the "Technical data" in the "Supplement".
Information:
If the medium reaches the transducer, buildup can form on it
and cause faulty measurements later on.
