level and interface or accept the values of the level measurement. The
entered value refers to the distance from the sealing surface of the
process fitting (sensor reference plane) to the total level or interface.
Linearization is required if the measured value should be outputted
in proportion to the volume and not the level. The linearization acts
identically on the level and the interface measurement. You can find
further linearization types in the extended adjustment.
If you have a non-linear vessel, you can select here the respective
linearization curve.
•
Linear
•
Spherical tank
•
Horizontal cylindrical tank
You must enter the following vessel dimensions with non-linear condi-
tions:
•
Height of the socket h
•
Vessel height D
In this window you can adjust the output signal. When the function is
inactive, you can change the settings via the "Extended adjustment".
These settings allow you to optimize the sensor. With them you can
compare a sounded distance with the indicated value and correct it, if
necessary.
Probe immersed in the liquid (covered)
Select whether or not the probe is immersed in the medium.
Measured distance to the medium
If the probe is immersed in the medium, you can enter here the meas-
ured distance to the medium.
Displayed distance correct?
Is the displayed distance value correct? If you have the possibility, you
can enter here the sounded distance to the medium.
False signal suppression
With this function you can carry out the automatic false signal sup-
pression. We recommend carrying out false signal suppression in any
case.
When the setup of the instrument is finished, additional settings can
be made. These are various backups and the locking of the instru-
ment against unauthorised or inadvertent adjustment.
Prepare a backup file of the instrument parameter adjustment?
For backup purposes, the current parameter adjustment of the instru-
ment is stored in a file. You can use this file later on to restore the
instrument parameter adjustment. The complete data set is down-
loaded from the device. This procedure can last several minutes.
