The selection "
Standpipe
" opens a new window in which the inner
diameter of the applied standpipe is entered.
Following the characteristics of the applications and the metrological
features of the sensor are described.
Note:
Probably the operation of the instrument in these applications is sub-
ject to national restrictions in respect to the radio license (see chapter
"
For your safety
"):
•
Plastic tank
•
Transportable plastic tank
•
Open water (gauge measurement)
•
Open flume (flow measurement)
•
Rain water overfall (weir)
Storage tank:
•
Setup: large-volumed, upright cylindrical, spherical
•
Medium speed: slow filling and emptying
•
Process/measurement conditions:
– Condensation
– Smooth product surface
– High requirements on measurement accuracy
•
Properties, sensor:
– Low sensitivity to sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy
– Short reaction time of the sensor not required
Storage tank with product circulation:
•
Setup: large-volumed, upright cylindrical, spherical
•
Medium speed: slow filling and emptying
•
Installations: small, laterally mounted or large, top mounted stirrer
•
Process/measurement conditions:
– Relatively smooth product surface
– High requirements on measurement accuracy
– Condensation
– Slight foam generation
– Overfilling possible
•
Properties, sensor:
– Low sensitivity to sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy, because not set for max. speed
– False signal suppression recommended
