2.2.3 Orientation
The device can basically be installed in any position in the piping.
Please note the following points however:
• The arrow indicated on the device must always point in the direction of flow.
• Measuring the flow of liquids in vertical pipes:
– There is vertical upward flow in the pipe = orientation recommended to avoid partial pipe
filling (see graphic, orientation A).
– There is vertical downward flow in the pipe = in this orientation it must be ensured that
the measuring tube is always completely full.
• In order to ensure that the maximum permissible ambient temperature for the transmitter is
not exceeded, the following orientations (see graphic) should be selected:
– Orientation A, C, D for a fluid temperature 200 °C (392 °F)
"Caution!
If the fluid temperature is 200 °C (392 °F), orientation B is not permitted for wafer
versions (Prowirl 73W) with nominal diameters DN 100 (4") and DN 150 (6").
