7 Set up with the integrated display and adjustment unit
VEGAPULS 31 • Two-wire 4 … 20 mA/HART
57820-EN-191014
– Very agitated surface, foam generation
– Fast to slow filling and emptying
– Vessel is filled and emptied very often
•
Properties, sensor:
– Higher measurement speed through less averaging
– Sporadic false echoes are suppressed
Dosing vessel
•
Vessel:
– All vessel sizes possible
•
Process/measurement conditions:
– Frequent and fast filling/emptying
– Tight installation situation
– Condensate and foam generation
– Buildup on the antenna
•
Properties, sensor:
– Optimization to measuring speed due to low averaging
– Suppression of sporadic false echoes
– False signal suppression recommended
Pump station/Pump shaft
•
Process/measurement conditions:
– Condensation on the sensor
– Contamination due to buildup, such as e.g. spider webs
– Partially strongly moved surface, dirt and grease deposits on
the shaft wall
•
Properties, sensor:
– Stable and reliable measured values through frequent averag-
ing
– Insensitive in the close range
– Insensitive to false echoes from buildup on the shaft walls
Overflow basin
•
Process/measurement conditions:
– Condensate formation, contamination due to buildup, e.g.
spider webs on the sensor
– Partly strongly agitated surface
•
Properties, sensor:
– Stable and reliable measured values through frequent averag-
ing
– Insensitive in the close range
– Insensitive to multiple echoes from the ceiling
Vessel/Collecting basin
•
Vessel:
– Large volume
– Upright cylindrical or rectangular
•
Process/measurement conditions:
– Slow filling and emptying
– Condensation
– Smooth product surface
•
Properties, sensor:
– Low sensitivity to sporadic false echoes
