2 or 4 traverses version
1. Fix a tensioning band for small or large nominal diameters as described on Page 18. Install the
second tensioning band (threaded stud on the opposite side). The second tensioning band must
still be moveable.
2. Determine the sensor distance.
!
Note!
To determine the sensor distance use:
– the “Sensor Installation” Quick Setup menu if the measuring device has a local operation.
Use the Quick Setup as described on Page 64. The sensor distance is shown in the POSI-
TION SENSOR function (i.e. a letter on the mounting rail for sensor 1 and a number for
sensor 2). The transmitter has to be installed and connected to the power supply to carry out
the “Sensor Installation” Quick Setup.
– the procedure described on Page 67 ff. if the measuring device has no local operation.
3. Arrange the tensioning bands to the sensor distance shown in the POSITION SENSOR func-
tion. Place the mounting rail on the threaded studs and then fasten the second tensioning band.
Remove the mounting rail.

4. Fix the sensor holder to the pipe using the threaded studs. Tighten the locking nuts using a
spanner (AF 13).
5. Fasten the mounting rail brackets to the sensor holders using a Philips screwdriver. Place the
mounting rail on the threaded studs and then fasten the appropriate srews.
6. Coat the contact surface of the sensors with an even (approx. 1 mm thick) layer of coupling
fluid (from the centre to the groove, see Page 73).
Then carefully insert the sensor into the sensor holder. Press the sensor cover onto the sensor
holder until you hear a click. Make sure that the arrows (

“close”) on the sensor housing
and sensor holder are pointing to each other. Then insert the sensor cable plug into the opening
provided and manually tighten the plug to the stop.
