6 Set up with the display and adjustment module

VEGAFLEX 83 • Modbus and Levelmaster protocol

41838-EN-130314

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

PAC Tw a r e .

The following circumstances cause interfering reections and can

inuence 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

reections 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 lling 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":
