3.2.3 Orientation
Vertical orientation
Recommended orientation with upward direction of flow (View A). Entrained solids sink down.
Gases rise away from the measuring sensor when fluid is not flowing. The piping can be completely
drained and protected against build-up.
Horizontal orientation
In the recommended installation range in a horizontal installation position (View B), gas and air
accumulation at the pipe cover and problematic build-ups at the bottom of the pipe have a minor
influence on the measurement.

3.2.4 Inlet and outlet runs (clamp-on version)
If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows, etc. If several
flow obstructions are installed, the longest inlet or outlet run must be considered. Compliance with
the following requirements for the inlet and outlet runs is recommended to ensure measuring accu-
racy.
