–
Measurement through the vessel top, if appropriate to the
application
–
Changed reflection conditions as well as jumps in measured
values when changing vessels
•
Further recommendations
–
When measuring through the tank ceiling, false signal sup-
pression via the operating tool
–
When measuring through the tank top in outdoor areas pro-
tective roof for the measuring point
Gauge measurement in waters
•
Process/measurement conditions:
–
Slow gauge change
–
Extreme damping of output signal in case of wave generation
–
Ice and condensation on the antenna possible
–
Floating debris sporadically on the water surface
Demonstration
•
Applications that are not typical level measurements, e.g. device
tests
–
Instrument demonstration
–
Object recognition/monitoring
–
Fast position changes of a measuring plate during functional
test
With " Bulk solid", the applications are based on the follow-
ing features, to which the measuring characteristic of the sensor is
adjusted in particular:
Silo (slender and high)
•
Process/measurement conditions:
–
Interfering reflections due to weld seams on the vessel
–
Multiple echoes/diffuse reflections due to unfavourable pour-
ing positions with fine grain
–
Varying pouring positions due to outlet funnel and filling cone
•
Further recommendations
–
False signal suppression via the operating tool
–
Alignment of the measurement to the silo outlet
Bunker (large-volume)
•
Process/measurement conditions:
–
Large distance to the medium
–
Steep angles of repose, unfavourable pouring positions due to
outlet funnel and filling cone
–
Diffuse reflections due to structured vessel walls or internals
–
Multiple echoes/diffuse reflections due to unfavourable pour-
ing positions with fine grain
–
Changing signal conditions when large amounts of material
slip off
•
