1.3 About the System
The water monitoring system is an operator station with an optional sampling system
which supplies the integrated sensor modules. The sensor modules measure PAH, turbidity,
pH and temperature in accordance with MEPC.184(59) and later MEPC.259(68). All
necessary validations of the sensor modules can be done locally using certified calibration
solutions which are fully compliant with IMO regulations.
The PAH Module measures the content of PAH in water as a phenanthrene equivalence as
specified by MEPC.259(68). The technique used is UV induced fluorescence with the
capability of detecting the PAH concentration in μg/l (ppb) in water. A special measuring
arrangement ensures a reliable and repeatable measurement while keeping the need for
cleaning at an absolute minimum. A unique feature is the local validation which ensures a
reliable measurement of PAH.
