● If the device is set for pressure measurement, no other measured variables (e.g. volume
flow) are available.
Example
For the pressure measurement, you set the following values, for example:
Damping value:
2.0 s
Lower range value:
0.0 bar
Upper range value:
5.0 bar
Application:
Pressure: linear (PRESS)
Unit:
bar
Lower scaling point:
-
Upper scaling point:
-

Level measurement
To set the application of the device for the level measurement, select the "level" characteristic
curve using the "Application" parameter (LEVEL).
For a level measurement, the device calculates the level height and the hydrostatic pressure.
The geometry of the vessel is not included in the calculation.
● The device uses a linear characteristic curve:
