7. Apply the coupling pad to the sensors with the adhesive side facing down. Alternatively
coat the contact surfaces with an even layer of coupling gel (approx. 1 mm (0.04 in)).
going from the groove through the center to the opposite edge.

pad)
8. Insert the sensor into the sensor holder.
9. Fit the sensor cover on the sensor holder and turn until the sensor cover engages with a
click and the arrows (▴ / ▾ "close") are pointing towards one another.
10. Insert the sensor cable into the sensor until the end stop.

 16 Mounting the sensor and connecting the sensor cable
The sensors can now be connected to the transmitter via the sensor cables and the
error message can be checked in the sensor check function. This completes the
mounting procedure.
• The visible measuring pipe surface must be clean (free from flaking paint and/or rust)
to ensure good acoustic contact.
• If the sensor is removed from the measuring pipe, it must be cleaned and new coupling
gel applied (if there is no coupling pad).
• On rough measuring pipe surfaces, the gaps in the rough surface must be filled with
sufficient amounts of coupling gel if the use of the coupling pad does not suffice
(installation quality check).
