Memosens sensor for measuring the concentration of polycyclic aromatic hydrocarbons in discharge water of marine exhaust gas cleaning systems (EGCS) and for reliable online monitoring of oil‑in‑water to ensure environmentally compliant discharge
The Memosens CFS51 fluorescence sensor accurately measures the PAH concentration in the inlet and outlet of marine gas scrubbers (ECGS) offering all benefits of the Memosens digital sensor technology.
The solid-state reference allows the ship's crew to calibrate and adjust the sensor directly on board, which helps extend the sensor's factory service interval to 4 years.
The sophisticated design of the assembly, as well as the angled installation position in which the assembly holds the sensor, prevents air bubbles from influencing the measured value.
For Exhaust Gas Cleaning Systems (ECGS), there is an all-in-one solution that incorporates the Memosens CFS51 PAH sensor, a pH sensor and a turbidity sensor. Click here for more information.

The rugged Memosens CFS51 fluorescence sensor enables continuous, real-time monitoring of PAHs and oil contamination in marine, industrial, and environmental waters. Compliant with MEPC.259(68) and MEPC.340(77), it is designed for PAH monitoring in EGCS wash water, where a solid-state reference enables onboard calibration for reliable measurement. The sensor also supports oil-in-water monitoring in industrial water systems, helping ensure stable process operation and compliant discharge.
The Memosens CFS51 fluorescence sensor is used for continuous monitoring of PAHs and oil contamination in the following applications:
Monitoring of PAHs in marine EGCS wash water
Effluent pollution monitoring
Detection of oil contamination in cooling water systems
Early identification of oil leakage in steam condensate from heat exchangers
Oil monitoring at seawater intakes of desalination plants
Continuous monitoring of surface water and environmental waters
Benefits
The uniquely long factory maintenance interval saves you a lot of costs and organizational effort
The optionally available flow assembly holds the sensor at the ideal installation angle to minimize disturbing influences caused by air bubbles. In addition, it can be tilted for quick mounting and dismounting of the sensor.
DNV approved integrated turbidity correction in the range of 0-50 FNU
High material compliance of sensor and flow assembly according to IACS E10 (flame retardancy)
The solid-state reference makes calibration very easy for the end user - and you can completely eliminate the need for toxic phenantrene, which increases safety for your employees and the environment
The suitability of the solid-state reference for calibration and readjustment of the PAH sensor on board was confirmed by DNV
Early warning to limit contamination and initiate appropriate measures, as well as real‑time monitoring to ensure reliable documentation and compliance with legal regulations
