Burkert Type 8112 - Manual (Page 15)

Fig. 8: Inflowing medium
To minimise flow resistance caused by the tuning fork, LEVEL
SWITCH
8112 should be mounted in such a way that the surfaces of
the blades are parallel to the product movement.
Due to the effects of agitators, equipment vibration or similar, the level
switch can be subjected to strong lateral forces. For this reason, do not
use an overly long extension tube for LEVEL SWITCH 8112, but check
if you can mount a level switch on the side of the vessel in horizontal
position.
Extreme vibration caused by the process or the equipment, e.g.
agitators or turbulence in the vessel, can cause the extension tube of
LEVEL SWITCH
8112 to vibrate in resonance. This leads to increased
stress on the upper weld joint. Should a longer tube version be
necessary, you can provide a suitable support directly above the
tuning fork to secure the extension tube.
This measure applies mainly to applications in Ex areas category 1G or
WHG. Make sure that the tube is not subject to bending stress due to
this measure.
