58340-EN-200806
Flow measurement flume/Overfall
•
Process/measurement conditions:
– Slow gauge change
– Smooth to agitated water surface
– Measurement often from a short distance with the demand for
accurate measurement results
– Ice and condensation on the antenna possible
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 following fea-
tures, 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 pouring
positions with fine grain
– Varying pouring positions due to outlet funnel and filling cone
•
Further recommendations
– False signal suppression via adjustment app or PACTware/DTM
– 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 pouring
positions with fine grain
– Changing signal conditions when large amounts of material slip
off
•
Further recommendations
– False signal suppression via adjustment app or PACTware/DTM
Heap (point measurement/profile detection)
•
Process/measurement conditions:
– Measured value jumps, e.g. through heap profile and traverses
– Large angles of repose, varying pouring positions
– Measurement near the filling stream
– Sensor mounting on movable conveyor belts
Crusher
