10.3.1 Setup
An application wizard guides you through the most common selection
possibilities. Further application options are available on the corre-
sponding DTM/app pages. A more detailed description of all available
application options is included in the DTM online help.
The following steps must be carried out in the application wizard:
Select application
Select from the offered options the application "
Flow measurement
flume/Weir
".
Assign measuring loop name
Assign a unique designation to the measuring point so that there can
be no confusion with other measuring points.
Define sensor characteristic values
The measuring range suitable for the application should be set di-
rectly in the sensor to achieve the maximum accuracy. This measuring
range must now be stored once again in the assistant together with
the sensor type and measuring unit.
Define application
Select the appropriate linearization and flume type. A list of available
flumes can be found in the introduction to this application.
