VEGAPULS 62 • 4 … 20 mA/HART - two-wire
36503-EN-161221
•
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:
Device mounting is limited to directly downward positioning only, and
cannot be operated while moving or in a ANY moving container. Only
the following antennas are approved for use in plastic containers:
75mmlledhornantenna,75mmhornantenna,75mmplastichorn
antenna, 95 mm horn antenna.
•
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:
Device mounting is limited to directly downward positioning only, and
cannot be operated while moving or in a ANY moving container. Only
the following antennas are approved for use in plastic containers:
75mmlledhornantenna,75mmhornantenna,75mmplastichorn
antenna, 95 mm horn antenna.

•
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
