be done by attaching the sensors threaded fitting to the
pressure pipe or through a dedicated load-lock system at
the chosen position on the pipe. Note however, that liquid
velocities are often high in pressurized pipes, and hence
there is an increased risk of sensor damage associated with
this type of measurements.
• In general it is recommended that the SulfiLogger™ sensor
is mounted in a way where it is either always submerged or
always out of the water (in the head space). Interpretation
of data can be difficult if the SulfiLogger™ sensor is intermit-
tently submerged. Furthermore, a mounting at a position
where the SulfiLogger™ sensor gets in and out of the water
often leads to an increased risk of biofouling and scaling,
which significantly limits the time with reliable data in a field
deployment.
