• Select
Yes
to apply the calibration curve for negative flow velocities as well. Select
No
if it is not to be used for negative
flow velocities.
14.2 ExpertUser mode
Some menu items that are not visible in the StandardUser mode are displayed.
14.2.1 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 preset limit. In this case an error will be output.

• 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 customized inputs are to be made.
• Select
Customized
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
will be displayed.
• 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
will be displayed.

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 measurement
failure when setting up a new measuring point.
Notice!
Some of the defined parameters remain activated when switching to the StandardUser mode. These parameters are
displayed but cannot be changed.
