The selection "Standpipe" opens a new window in which the inner
diameter of the applied standpipe is entered.
The following features form the basis of the applications:
Storage tank:
•
Setup: large-volumed, upright cylindrical, spherical
•
Product speed: slow filling and emptying
•
Process/measurement conditions:
– Condensation
– Smooth product surface
– Max. requirement to the measurement accuracy
Storage tanke with product circulation:
•
Setup: large-volumed, upright cylindrical, spherical
•
Product speed: slow filling and emptying
•
Vessel: small laterally mounted or large top mounted stirrer
•
Process/measurement conditions:
– Relatively smooth product surface
– Max. requirement to the measurement accuracy
– Condensation
– Slight foam generation
– Overfilling possible
Storage tank on ships (Cargo Tank):
•
Product 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 %
Stirrer vessel (reactor):
•
Setup: all vessel sizes possible
•
Product speed:
– Fast to slow filling possible
– Vessel is very often filled and emptied
•
Vessel:
– Socket available
– Large agitator blades of metal
– Vortex breakers, heating spirals
•
Process/measurement conditions:
– Condensation, buildup by movement
