Level Measurement - Siemens SITRANS P Operating Instructions Manual

● 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:
Lower range value:
Upper range value:
Application:
Unit:
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:
