4.3 Installation
4.3.1 Mounting the insertion sensor
The sensor can be mounted into a welding socket or a retractable mounting set. If a retract-
able 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 Hauser welding socket. If a welding boss
is already available or a customer-specific one 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

• The welding socket is made of stainless steel 1.4404 (316/316L). Use appropriate weld-
ing 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 a 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

Insertion depth calculation and adjustment
To ensure optimum measurement performance, the insertion sensor must be installed in the
correct position in the pipe or duct (30% of the internal diameter).
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:
