6 Set up the sensor with the display and adjustment module
VEGAPULS 63 • Modbus and Levelmaster protocol
41364-EN-170711
– Entering the tube inside diameter takes the running time shift
into consideration
– Echo detection sensitivity reduced
Bypass:
•
Medium speed:
– Fastuptoslowllingwithshortuptolongbypasstubepossible
– Often the level is hold via a control facility
•
Vessel:
– Lateral outlets and inlets
– Joinslikeanges,weldjoints
– Shifting of the running time in the tube
•
Process/measurement conditions:
– Condensation
– Buildup
– Separation of oil and water possible
– Overllingintotheantennapossible
•
Properties, sensor:
– Measurementspeedoptimizedthroughlittleaveraging
– Entering the tube inside diameter takes the running time shift
into consideration
– Echo detection sensitivity reduced
– False signal suppression recommended
Plastic tank:
•
Vessel:
– Instrumentxmountedorbuiltin
– Measurement through the vessel top, if appropriate to the
application
– With empty vessel, the measurement can go through the bot-
tom
•
Process/measurement conditions:
– Condensation on the plastic ceiling
– In outdoor facilities, water and snow on vessel top possible
•
Properties, sensor:
– False signals outside the vessel are not taken into consideration
– False signal suppression recommended
Transportable plastic tank:
•
Vessel:
– Materialandthicknessdierent
– Measurement through the vessel top
•
Process/measurement conditions:
– Measured value jump with vessel change
•
Properties, sensor:
– Quickadaptationtochangingreectionconditionsduetoves-
sel change
– False signal suppression required
Open water (gauge measurement):
•
Rate of level change: slow level change
•
Process/measurement conditions:
– Large distance from sensor to water surface
