7.3.3 Installation of the sensor
7.3.3.1 Preparation of the pipe
ATTENTION: The preparation of the pipe can be carried out even on pressurized lines by using
special machinery. Aside from the fact that this operation requires the use of special equipment, it
is also intrinsically dangerous. Thus, it is recommended to rely exclusively on highly specialized
personnel.
ATTENTION: Before inserting the sensor, check that the insertion hole is free from obstruction
and/or burrs caused by preparation work because it could damage the device.
Drill the pipe at the installation point.
The diameter of the hole must be Ø
25 ± 1mm.
Weld the threaded sleeve, paying
the utmost attention to its correct
orientation.
The axis of the sleeve must
intersect the axis of the pipe and be
perpendicular to it.
Install the valve, use PTFE tape to
ensure the tightness of the thread.
Close the valve and pressurize the
pipe if necessary.

7.3.3.2
Assembly of the flowmeter
Install the insertion meter,
making sure that the stem
is completely retracted to
prevent the head with the
electrodes from hitting the
valve.
Use PTFE tape to ensure
the tightness of the thread.
1. Open the valve
completely
2. Adjust the insertion
depth
3. Adjust the alignment in
relation to the pipe axis.
The alignment precision
must be within ±2°.
Tighten the lock nut by
applying a tightening
torque of 40Nm (30 ft-lb).
Connect the safety chain
by adjusting its length.
