After choosing a suitable coupling medium, spread it lightly around the locations chosen for installing the
probes and copiously on the probes themselves.
3) Installing the probe
Attach the probes onto the pipe using straps or a dedicated support. Check the presence and continuity of
the coupling medium (ensure no air layer forms between the pipe wall and the probe). To avoid this pitfall,
refrain from sliding the probes too much (the coupling medium film could be altered/broken).
4.4.3. Inserted probes
Preliminary comment : before you do anything, you must check with Ultraflux whether your probes can be
extracted under load or not. Whether an inserted probe may be extracted under load or not is determined
by the probe used and the application conditions of your measuring point (pressure, fluid measured, etc.).
