VEGAPULS C 21 • Modbus and Levelmaster protocol
58343-EN-200806
– Multiplereectionsthroughatvesselceiling
– Condensation, dirt deposits on the sensor
– Flooding of the sensor antenna
Vessel/Collecting basin
•
Vessel:
– Large volume
– Upright cylindrical or rectangular
•
Process/measurement conditions:
– Slowllingandemptying
– Smooth medium surface
– Condensation
Plastic tank (measurement through the vessel top)
•
Process/measurement conditions:
– Measurement through the tank top, if appropriate to the applica-
tion
– Condensation on the plastic ceiling
– In outdoor facilities, water and snow on vessel top possible
•
Further recommendations
– With measurement through the tank top false signal suppres-
sion via adjustment app or PACTware/DTM
– When measuring through the tank top in outdoor areas protec-
tive roof for the measuring point
Transportable plastic tank (IBC)
•
Process/measurement conditions:
– Materialandthicknessdierent
– Measurement through the vessel top, if appropriate to the
application
– Changedreectionconditionsaswellasjumpsinmeasured
values when changing vessels
•
Further recommendations
– With measurement through the tank top false signal suppres-
sion via adjustment app or PACTware/DTM
– When measuring through the tank top in outdoor areas protec-
tive roof for the measuring point
Gauge measurement in waters
•
Process/measurement conditions:
– Slow gauge change
– Extreme damping of output signal in case of wave generation
– Ice and condensation on the antenna possible
– Floating debris sporadically on the water surface
Flowmeasurementume/Overfall
•
Process/measurement conditions:
– Slow gauge change
– Smooth to agitated water surface
– Measurement often from a short distance with the demand for
accurate measurement results
– Ice and condensation on the antenna possible
