Storage tank on ships (Cargo Tank):
•
Medium speed: slow filling and emptying
•
Vessel:
– Installations in the bottom section (bracers, heating spirals)
– High sockets 200 … 500 mm, also with large diameters
•
Process/measurement conditions:
– Condensation, buildup by movement
– Max. requirement on measurement accuracy from 95 %
•
Properties, sensor:
– Low sensitivity to sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy
– False signal suppression required
Stirrer vessel (reactor):
•
Setup: all vessel sizes possible
•
Medium speed:
– Fast to slow filling possible
– Vessel is filled and emptied very often
•
Vessel:
– Socket available
– Large agitator blades of metal
– Vortex breakers, heating spirals
•
Process/measurement conditions:
– Condensation, buildup by movement
– Strong spout generation
– Very agitated surface, foam generation
•
Properties, sensor:
– Higher measurement speed through less averaging
– Sporadic false echoes are suppressed
Dosing vessel:
•
Setup: all vessel sizes possible
•
Medium speed:
– Fast filling and emptying
– Vessel is filled and emptied very often
•
Vessel: tight installation situation
•
Process/measurement conditions:
– Condensation, buildup on the antenna
– Foam generation
•
Properties, sensor:
– Measurement speed optimized by virtually no averaging
– Sporadic false echoes are suppressed
– False signal suppression recommended
Standpipe:
•
Medium speed: very fast filling and emptying
•
Vessel:
