9.2 Description of the applications
This menu item enables you to optimally adapt the sensor to the ap-
plication, the place of use and the measuring conditions. The adjust-
ment possibilities depend on the selection made under "
Medium
", "
Liquid
" or "
Bulk solid
".
The vessels as well as the measuring and process conditions are
described in the following as an overview.
With "
Liquid
", the applications are based on the following features,
to which the measuring characteristic of the sensor is adjusted in
particular:
Storage tank
•
Vessel:
– Large volume
– Upright cylindrical, horizontal round
•
Process/measurement conditions:
– Slow filling and emptying
– Smooth medium surface
– Multiple reflections from dished vessel ceiling
– Condensation
Stirrer vessel
•
Vessel:
– Large agitator blades of metal
– Installations like flow breakers, heating spirals
– Nozzle
•
Process/measurement conditions:
– Frequent, fast to slow filling and emptying
– Strongly agitated surface, foam and strong vortex generation
– Multiple reflections through dished vessel ceiling
– Condensation, buildup on the sensor
•
Further recommendations
– False signal suppression with running agitator via adjustment
app or PACTware/DTM
Dosing vessel
•
Vessel:
– Small vessels
•
Process/measurement conditions:
– Frequent and fast filling/emptying
– Tight installation situation
– Multiple reflections through dished vessel ceiling
– Product buildup, condensate and foam generation
Pumping station/Pump shaft
•
Process/measurement conditions:
– Partly strongly agitated surface
– Installations such as pumps and ladders
– Multiple reflections through flat vessel ceiling
– Dirt and grease deposits on shaft wall and sensor
– Condensation on the sensor
