Coat the contact surfaces of the sensors with an even layer of coupling fluid approx. 1 mm
(0.04") thick, going from the groove through the center to the opposite edge.

Note!
• Avoid to use a thick layer of the coupling fluid (less is more).
• Clean and reapply new coupling fluid when the sensor is removed from the pipe.
• On rough pipe surface e.g. GRP pipes ensure that the gaps crevices within the surface roughness
are filled. Apply suffizienet copling fluid.
