VEGABAR 66 can be used for level as well as for process pressure
measurement. Default setting is level measurement. The mode can be
changed in the adjustment menu.
Depending on the application only the respective subchapter "Level
or process pressure measurement" is of importance. There, you find
the individual adjustment steps.
Level measurement
Set up VEGABAR 66 in the following sequence:
1. Selecting adjustment unit/density unit
2. Carry out a position correction
3. Carry out min. adjustment
4. Carry out max. adjustment
In the menu item "Adjustment unit" you select the physical unit in
which the adjustment should be carried out, e.g. mbar, bar, psi...
The position correction compensates the influence of the mounting
position or static pressure on the measurement. It does not influence
the adjustment values.
