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

2 VEGABAR 81 - Slave sensor

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.
