VEGAPULS 63 • Modbus and Levelmaster protocol
41364-EN-130228
– With empty vessel, the measurement can be carried out
through the bottom
•
Process/measurement conditions:
– Condensation on the plastic ceiling
– In outside facilities water and snow on the vessel top possible
Transportable plastic tank:
•
Vessel:
– Material and thickness different
– Measurement through the vessel top
•
Process/measurement conditions:
– Measured value jump with vessel change
Open water (gauge measurement):
•
Gauge rate of change: slow gauge change
•
Process/measurement conditions:
– Distance sensor to water surface to big
– Extreme damping of output signal due to wave generation
– Ice and condensation on the antenna possible
– Spiders and insect nestle in the antennas
– Floating material and animals sporadically on the water surface
Open flume (flow measurement):
•
Gauge rate of change: slow gauge change
•
Process/measurement conditions:
– Ice and condensation on the antenna possible
– Spiders and insect nestle in the antennas
– Smooth water surface
– Exact measurement result required
– Distance to the water surface normally relatively high
Rain water overfall (weir):
•
Gauge rate of change: slow gauge change
•
Process/measurement conditions:
– Ice and condensation on the antenna possible
– Spiders and insect nestle in the antennas
– Turbulent water surface
– Sensor flooding possible
Demonstration:
•
Adjustment for all applications which are not typically level meas-
urement
•
Sensor accepts all measured value changes within the measuring
range immediately
•
Typical applications:
– Instrument demonstration
– Object recognition/monitoring (additional settings required)
Caution:
If a separation of liquids with different dielectric figure occurs in the
vessel, for example through condensation, the radar sensor can
detect under certain circumstances only the medium with the higher
