3.3 Installation instructions
3.3.1 Mounting the insertion sensor
The sensor can be mounted into a welding socket or a retractable mounting set. If a retractable
mounting set is being used, then refer to the supplementary documentation delivered with the
mounting set.
Mounting the welding socket
This instruction describes mounting of the Endress+Hauser welding socket. If an existing or
customer-specific mounting set is being used, then go to the next section "Insertion depth
calculation and adjustment".
!
Note!
• Take the orientation and inlet and outlet runs into account before mounting the welding
socket ä 14 ff.
• The welding socket is made of stainless steel 1.4404 (316/316L). Use appropriate welding
technique.
"
Caution!
When mounting the fitting to a thin wall duct, use a suitable support bracket for the sensor and weld
the welding socket to a base plate to spread the load. Otherwise, the mounting may be unstable and
the duct wall can be damaged.
#
Warning!
• These instructions are only applicable to installation in an un-pressurized line, without gas present
and at safe temperatures.
1. Drill or cut hole of Ø 31.0 mm ± 0.5 mm (1.22" ± 0.019") in the pipe.
2. Deburr the hole.
3. Fit the edge of the welding socket into hole, align it vertically and weld it on  å 9.

Insertion depth calculation and adjustment
To obtain the best measurement results, it is important that the sensor is inserted at the right
insertion depth in the pipe/duct. A millimeter and inch scale is provided along the entire length of
the sensor tube. This makes it possible to align the sensor at the right depth.
4. Calculate the insertion depth:
– with the help of the Quick Setup "Sensor"  ä 51 or
– using the following dimensions and formulae
