Mounting of sensor
Basically, the sensor can be mounted in any orientation. However, an overhead mounting (sensor
face looking down) is favourable, since the sensor will be less contaminated.
The sensor must be installed so that the weld seam runs right-angled to the direction of motion. It
must be assured, that all rollers of the sensor are contacting the tube and turn when the tube
rotates. The provided rubber mounts are intended for the installation of the sensor. Thus the sensor
adapts to the tube.

Fig. 6: Mounting of sensor
The sensor mounting bracket substantially influences the correct function. If the sensor is mounted
in a rigid mounting bracket, it can happen that the sensor contacts the tube only at one side. This
will lead to unwanted one-sided pressure distribution on the sensor. In addition, such uneven
contact with the tube provokes faulty measurements.
Thus the sensor should be mounted using the provided rubber buffers as well as an air cylinder
(see next picture). The sensor does not need to be pressed onto the tube, the own weight of the
sensor is sufficient.
Depending on mechanical arrangement, it might be necessary to equip the sensor bracket with
springs.

Description
For the explanation of
principle the sensor is shown
here under the tube. In the
practical case, the sensor
should be preferably set
above the tube.
