15.12.13 Resetting the default values of all the differentiation factor
parameters
To reset all the default values of the DF parameters, do the following:
→
Go to the CONFIGURATION view.
→
SAW sensor
→
Confirm to access the Parameter view.
→
Add. meas. values DF
→
Reset to default Confirm.
All the DF parameters are reset.
→
Go back to the parent menu.

If different liquids with different DFs may flow through the pipe, you can identify the liquid flowing through
the pipe at a given time.

Fig. 62: Ranges of the DF for different liquids flowing through the pipe
To identify the liquid flowing through the pipe, do the following:
→
Connect an analogue output or a digital output configured as a frequency output to a PLC for example.
→
Associate the DF to the used analogue output or digital output. See chapter 18.3.1 Changing the
process value and the process value range associated to an analogue output or chapter 18.5.3 Config -
uring a digital output as a frequency output.
→
Make sure you exactly know the ranges of the DF values for the different liquids that may flow through
the pipe.
→
If necessary, choose the type of temperature compensation for one of the liquids. See chapter 15.12.10 .
→
Configure the ranges in the PLC so that you can clearly identify which liquid is flowing through the pipe.
