VEGAPULS 66 • Modbus and Levelmaster protocol
41366-EN-121011
•
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
dielectric figure. Keep in mind that layer interfaces can cause faulty
measurements.
