VEGAFLEX 83 • Modbus and Levelmaster protocol

In the menu "HART variables 2" you can have the third HART value
TV (third value) and the fourth HART value QV (quarter value) of the
sensor displayed.
The values cannot be changed in the display and adjustment module.
To change these values, you have to use the adjustment software
PACTware.
The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
Note:
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for the level and
interface measurement. We generally recommend carrying out a false
signal suppression to achieve the best possible accuracy. This should
be done with the lowest possible level so that all potential interfering
reflections can be detected.
Proceed as follows:
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
echo. The filling level would then no longer be detectable in this area.
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":
