Installation for measurement as dual-path insertion version

1. Determine the installation area (e) on the pipe section:
– Mounting location  ä 11
– Inlet/outlet run  ä 12
– Space required by the measuring point: approx. 1× pipe diameter.
2. Mark the middle line on the pipe at the mounting location.

3. At the mounting location of the sensor holder, mark the length of the arc (b) to one side of the
middle line. Usually, the arc length is taken as approx. 1/12 of the pipe circumference.
Indicate the first drillhole (drillhole diameter approx. 81 to 82 mm / 3.19 to 3.23").
!
Note!
Make the lines longer than the drillhole!
4. Cut the first hole, e.g. with a plasma cutter. Measure the wall thickness of the pipe if it is not
known.

5. Determine the space between the distancing holes (sensor distance) and the arc length
between the sensors of the measuring groups.
!
Note!
Determine the sensor distance as follows:
– Via the Quick Setup "Sensor Installation" for measuring devices with local operation.
Run the Quick Setup as described on  ä 84. The sensor distance is displayed in the
SENSOR DISTANCE function (6886) and the arc length in the ARC LENGTH function
(6887). The transmitter must be installed and connected to the power supply before you can
run the "Sensor Installation" Quick Setup.
– As explained on  ä 84 for transmitters without local operation.
