the volume percentage of the vessel is displayed correctly. If the
volume should not be displayed in percent but e.g. in l or kg, a scaling
can be also set in the menu item "Display".

n this menu item you can enter an unambiguous designation for the
sensor, e.g. the measurement loop name or the tank or product
designation. In digital systems and in the documentation of larger

jump to the main menu with the [ESC] key.
H
igh sockets or vessel installations, such as e.g. struts or agitators as
well as buildup and weld joints on the vessel walls cause interfering
reflections which can impair the measurement. A false echo storage
detects and marks these false echoes, so that they are no longer taken
into account for the level measurement. A false echo memory should
be created with empty vessel so that all potential interfering reflections
will be detected.
P
robes in coax version require no gating out of false echoes since they
are not influenced by false reflections.
