Floating material and animals sporadically on the water
surface
Open flume (flow measurement):
l Gauge rate of change: slow gauge change
l 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):
l Gauge rate of change: slow gauge change
l Process/measurement conditions:
-
Ice and condensation on the antenna possible
-
Spiders and insect nestle in the antennas
-
Turbulent water surface
-
Sensor flooding possible
Demonstration:
l Adjustment for all applications which are not typically level
measurement
l Sensor accepts all measured value changes within the measuring
range immediately
l 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 measure-
ments.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially
designed for interface measurement.
