Configuring the measuring device
9.3.1
Configuration of the level measurement
The first parameters of the
Setup
menu are used to configure the measurement. A short
description is given in the following sections. For a more detailed description refer to the
parameter description in the appendix → 118.
Basic settings
Navigation path: Setup
Parameter
Meaning
Description
Setup → Device tag
Define a name to identify the measuring point within the plant.
Setup → Units preset
Select a set of units for length, pressure and temperature.
Setup → Tube
diameter
Enter the diameter of the stilling well.
Setup → Empty
Enter the distance from the lower edge of the device flange to the datum
plate.
Setup → Tank level
Shows the measured level.
Check whether the indicated value matches the actual level.
Setup → Set level
Can be used to correct a constant shift of the measured level.
If the indicated level does not match the actual level: Enter the actual
level into this parameter.
An offset for the measured level is then automatically defined.
The
Set level
parameter can only be used to compensate for a constant level error. To
eliminate errors resulting from interference echos, use the interference echo
suppression (map).

Setup → Distance
Shows the measured distance from the lower edge of the device flange to
the product surface. Check whether this value is correct.
Setup → Confirm
distance
Specify whether the measured distance matches the actual distance. The
selection determines up to which distance an interference echo suppression
is recorded.

Determines up to which distance the new mapping will be recorded.
Depending on the selection in
