certain circumstances only the medium with the higher dielectric
constant. Keep in mind that layer interfaces can cause faulty meas-
urements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de-
signed for interface measurement.
The following options are available when "Bulk solid" is selected:
The following features form the basis of the applications:
Silo (slender and high):
•
Vessel of metal: weld joints
•
Process/measurement conditions:
– Filling aperture too close to the sensor
– System noise in completely empty silo increased
•
Properties, sensor:
– Stable measured values through higher averaging
– False signal suppression during setup recommended, required
for automatic false signal suppression
– Automatic false signal suppression with partly filled vessel
Bunker (large-volume):
•
Vessel of concrete or metal:
– Structured vessel walls
– Installations present
•
Process/measurement conditions:
– Large distance to the medium
– Large angles of repose
•
Properties, sensor:
– Mean averaging
– High measured value jumps are accepted
Bunker with fast filling:
•
Vessel of concrete or metal, also multiple chamber silo:
– Structured vessel walls
– Installations present
•
Process/measurement conditions:
– Measured value jumps, e.g. through truck loading
– Large distance to the medium
– Large angles of repose
•
Properties, sensor:
– Lower averaging
– Very high measured value jumps are accepted
Heap:
•
Sensor mounting on movable conveyor belts
•
Detection of the heap profile
•
Height detection during filling
