3. Adjust the sensor distance by moving the sensors (a) along the assembly frame
and tighten the sensor fixing nuts (b). You may freely choose the sensor’s position
within the adjustment range.
Rotate the sensor adjustment screw counter-clockwise (c) so that the sensor is
moved up inside the mounting rail. Apply coupling fluid to the sensors as described
on Page 45.

4. Installation of U sensor assembly:
Locate the sensor assembly on the pipe as shown in the graphic below. Place the
tensioning bands across the saddles at the frame ends of the sensor assembly.
Tighten the bands by hand and fix them by pressing the band’s rough surfaces
together. Lower the sensors by rotating the sensor adjustment screw (e) clockwise
until the sensor surface makes contact with the pipe surface. Then connect the
upstream and downstream BNC cables to the sensors (f).
