13.2 ExpertUser mode
Some menu items that are not visible in the StandardUser mode are displayed.
Limit of the flow velocity
Single outliers caused by heavily disturbed surroundings can appear among the measured values of the flow velocity. If
these outliers are not ignored, they will affect all derived physical quantities, which will be unsuitable for the integration
(e.g., pulse outputs).
In the ExpertUser mode it is possible to enter a limit for the flow velocity.
It is possible to ignore all measured flow velocities higher or lower than the default limit. If a measured value exceeds or is
below the default limit, it will be output as error.

.
• Press ENTER until the menu item
Flow velocity limit
is displayed.
• Select
Off
if no limit for the flow velocity is to be used.
• Select
Default
if no user-defined inputs are to be made.
• Select
User-defined
to define a limit for the flow velocity.
• Press ENTER.
• Enter a limit of the flow velocity for the measurement in flow direction.
• Press ENTER.
If the flow velocity is higher than this limit, it will be marked as invalid. The physical quantity cannot be determined.
UNDEF
and an exclamation point will be displayed after the physical quantity and the unit of measurement of the flow velocity, see
Fig. 13.1.
• Enter a limit of the flow velocity for the measurement against the flow direction.
• Press ENTER.
If the flow velocity is lower than this limit, it will be marked as invalid. The physical quantity cannot be determined.
UNDEF
and an exclamation point will be displayed after the physical quantity and the unit of measurement of the flow velocity, see
Fig. 13.1.
Notice!
The ExpertUser mode is intended for experienced users with advanced application knowledge.
Changed parameters can affect the StandardUser mode and lead to wrong measured values or to a failure of the
measurement when setting up a new measuring point.
Notice!
Some of the defined parameters remain active after the activation of the StandardUser mode. These parameters are
displayed but cannot be changed.
