10 Handbook BM 100 A
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 process connection near to these objects.
Probe Type
Recommended minimum distance of probe from
objects inside the tank in millimetres (inches)
