VEGABAR 81 • Slave sensor for electronic differential pressure
45049-EN-131011
The interface measurement is possible in open as well as in closed
vessels.
4.7 Density measurement
The master/slave combination is suitable for density measurement.
Requirements for a functioning measurement are:
•
Vessel with changing level
•
Product with consistent density
•
Distance between the measurement points as large as possible
•
Level always above the upper measuring point

Density measurement is possible in open as well as in closed ves-
sels. Small changes in the density cause only small changes in the
measured differential pressure. So a suitable measuring range has to
be selected.
