Preparation

Determining the installation point
The installation point should be easily accessible and experience
only low vibrations. The ambient temperature must not exceed the
values specified in the technical data (pay attention to possible heat
radiation).
Please note that a clearance of at least 400 mm is required for
deinstallation of the sensor. When planning the measuring point,
this is in addition to the space required for the measurement fitting
or tap of at least 95 mm, or the space for the existing fittings (also
including possible reductions to DN 15).
During assembly, consider the flow direction and required
inflow/outflow routes.
Also consider the installation point with regard to the specified
technical data. The medium may not be in a condensed state at the
installation point. For this reason, the location in a working
compressed air network can only be behind a suitable compressed
air dryer which provides a suitable pressure dew point; otherwise
the specified measurement accuracy is not guaranteed.
Do not install the sensor in the crossed-out installation positions
shown in the following graphic. In the event of a limited flow, the
specified accuracy cannot be maintained.
