VEGAPULS 63 • Modbus and Levelmaster protocol
6 Set up the sensor with the display and adjustment module
– High sockets 200 ... 500 mm, also with large diameters
Process/measurement conditions:
– Condensation, buildup by movement
– Max. requirement on measurement accuracy from 95 %
Properties, sensor:
– Low sensitivity to sporadic false echoes
– Stable and reliable measured values through averaging
– High accuracy
– False signal suppression required
Stirrer vessel (reactor):
Setup: all vessel sizes possible
Medium speed:
– Fast to slow filling possible
– Vessel is filled and emptied very often
Vessel:
– Socket available
– Large agitator blades of metal
– Vortex breakers, heating spirals
Process/measurement conditions:
– Condensation, buildup by movement
– Strong spout generation
– Very agitated surface, foam generation
Properties, sensor:
