2.6.1.2 Mounting instructions
Check that the monitoring head is suitable for the medium to be monitored. The
monitoring head must only be used for media against which the sensor material is
sufficiently chemically or corrosion resistant.
When using titanium, particularly according to category 1, installation has to ensure
that impact and friction sparks cannot occur.
❏ Compare monitoring head with pipe fitting and check, whether fitting or T-piece have the
corresponding internal thread and whether the length of the process connection is correct.
❏ The two sensors (M) should be screwed into the pipeline far enough to ensure that they are
aligned side by side directly across the direction of flow. The sensors are correctly positioned
when the wrench flats (S) are aligned parallel with the pipeline.

S
Vertical pipelines:
Medium should be rising.
Horizontal pipelines:
Monitoring head should be
mounted on the underside.
The two sensors must be
side by side across the
direction of flow.
The surface of the shaft
end should project into
the inner pipe wall
(approx. 1-2 mm).
