3. Select the mounting location of the sensors with the given sensor distance and
optimum inlet run conditions,. In doing so, ensure there is nothing impeding sensor
mounting over the entire circumference of the measuring pipe.
4. Fit two strap bolts over strapping band 1 and guide approx. 50 mm (2 in) of one of
the strapping band ends into one of the two strapping band locks and into the lock.
Then guide the protective flap over this strapping band end and lock in place.
5. Position strapping band 1 as perpendicular as possible to the measuring pipe axis
without twisting it.
6. Guide the second strapping band end through the strapping band lock that is still free
and proceed in the same way as for the first strapping band end. Guide the protective
flap over the second strapping band end and lock in place.
7. Tighten strapping band 1 as tightly as possible by hand.
8. Align strapping band 1 in the desired position and place it as perpendicular as
possible to the measuring pipe axis.
9. Position the two strap bolts on strapping band 1, arranging them at a half
circumference in relation to one another (180° arrangement, e. g. 7:30 o' c lock and
1:30 o' c lock) or quarter circumference (90° arrangement, e.g. 10 o' c lock and 7
o' c lock).
10. Tighten strapping band 1 so that it cannot slip.
11. Strapping band 2: proceed as for strapping band 1 (steps 4 to 8).
12. Slightly tighten strapping band 2 for final assembly. It must be possible to move
strapping band 2 for final alignment. The distance/offset from the center of
strapping band 2 to the center of strapping band 1 is indicated by the sensor distance
of the device.
13. Align strapping band 2 so that it is perpendicular to the measuring pipe axis and
parallel to strapping band 1.
14. Position the two strap bolts on strapping band 2 on the measuring pipe so they are
parallel to one another and offset at the same height/clock position (e. g. 10 o' c lock
and 4 o' c lock) in relation to the two strap bolts on strapping band 1. A line drawn on
the measuring pipe wall in parallel with the measuring pipe axis can be helpful here.
Now set the distance between the center of the strap bolts at the same level so that it
exactly matches the sensor distance. Alternatively, you can use the wire length here
→  38.
15. Tighten strapping band 2 so that it cannot slip.
WARNING
L
Risk of injury due to sharp edges!
‣
After shortening the strapping bands, trim the cut edges.
‣
Wear suitable protective goggles and safety gloves.
