Example
For the volume measurement, you set the following values, for example:
Damping value: 2.0 s
Lower range value: 0.0 mbar
Upper range value: 500.0 mbar
Application: Cylinder vessel (CYLIN)
Unit: m
3
Lower scaling point: 0.0 m
3
Upper scaling point: 10.0 m

2. Select the "Application" parameter [05].
3. Select the parameter value.
Application [05] (Page 110)
9.2.5 Application point [06]
Sets the application point from which scaling occurs according to the square root. Before the
application point, the scaling occurs in a linear relationship with the differential pressure.
This parameter is only visible when you have selected the characteristic curve "Linear, square
root" (VSLIN or MSLIN) using the "Application" parameter.
Setting range: 5 to 15%
Factory setting: 10%
