Weighting factor
The weighting factor is used for transducers installed on the same pipe in order to compensate differences between the
measured values of the flow velocity of different channels.
The differences can be caused by profile deformations or transverse flows. These influences can be reduced by averaging
the measured values of several channels. If a channel has a temporarily malfunction, the average will change abruptly. In
order to avoid differences, all channels have to be adjusted with the weighting factor.
The weighting factor for the channel x results from the flow velocity v
x
and the average flow velocity of all channels v

The weighting factor can be activated in the transmitter.
• Select the menu item Special settings in the program branch Options.
• Press ENTER until the menu item Weighting factor is displayed.
•Select Off to measure without the weighting factor.
•Select Default if no user-defined inputs are to be made.
•Select On to define the value for the weighting factor.
• Press ENTER.
Transducer temperature and transducer temperature violation as diagnostic value
When configuring outputs, the list items Transducer temp. and Transd. temp. violat. are available in the menu
item Diagnostic values. The diagnostic values can either be transmitted via the output of the transmitter or defined as
source of the event trigger. The diagnostic value Transducer temp. is available on physical channels only.
•Select Diagnostic values as source item.
• Press ENTER.
• Select a list item for the quantity to be output, see Tab. 13.2.
• Press ENTER.
