7 Set up with the integrated display and adjustment unit
VEGAPULS 31 • Two-wire 4 … 20 mA/HART
57820-EN-191014
– Stable and reliable measured values through averaging
– High measurement accuracy
– Short reaction time of the sensor not required
Plastic tank (measurement through the vessel top)
•
Process/measurement conditions:
– Condensation on the plastic ceiling
– In outdoor facilities, water and snow on vessel top possible
– Measurement through the vessel top, if appropriate to the
application
•
Properties, sensor:
– False signals outside the vessel are not taken into consideration
– False signal suppression recommended
Transportable plastic tank (IBC)
•
Process/measurement conditions:
– Material and thickness different
– Measured value jump with vessel change
– Measurement through the vessel top, if appropriate to the
application
•
Properties, sensor:
– Quick adaptation to changing reflection conditions due to ves-
sel change required
– False signal suppression required
Gauge measurement in waters
•
Process/measurement conditions:
– Slow gauge change
– Extreme damping of output signal due to wave generation
– Ice and condensation on the antenna possible
– Floating debris sporadically on the water surface
•
Properties, sensor:
– Stable and reliable measured values through frequent averag-
ing
– Insensitive in the close range
Flow measurement flume/Overfall
•
Process/measurement conditions:
– Slow gauge change
– Ice and condensation on the antenna possible
– Smooth water surface
– Exact measurement result required
•
Properties, sensor:
– Stable and reliable measured values through frequent averag-
ing
– Insensitive in the close range
Demonstration
•
Adjustment for all applications which are not typically level meas-
urements
– Instrument demonstration
– Object recognition/monitoring (additional settings required)
•
