Direction of flow
The direction of flow must be taken into account when installing the
measurement fitting. This is shown on the tapping clamp by means
of an arrow (Compac-Air system). The arrow points in the direction
in which the medium in the pipeline flows.
If only the electronic sensor with PBCOver reverse running protec-
tion is used, then make sure the sensor display points against the
direction of flow.

The sensor must be parallel to the direction of flow.
Angular displacement leads to severe measurement
errors.
