BM 102 13
1 Agitator
2 Support beam perpendicular to the
pulse direction
3 Abrupt changes in tank cross section
4 Heating tubes
5 Alternative solution: reference chamber
-electromagnetic field is contained
within chamber
6 Gauge electromagnetic field:
Any intruding metallic object will be
detected in this zone if perpendicular to
the emitted pulse direction.
= Do not fit the gauge near to these objects.
