Oil in Water Analysers – Advanced Sensors

Improving water quality monitoring – Analytical Experts

The introduction of Advanced Sensors revolutionary oil in water analysers was a step change in technology.

The EX-100 was the first low maintenance analyser to provide continuous uninterrupted accurate and repeatable measurement of oil concentrations. Oil companies could now meet their regulatory oil in water discharge requirements with confidence.

Reliable real time data enabled the next step to improved efficiency of their separation processes, saving money and resources, and reducing downtime.

Advanced Sensors has developed a wide portfolio of low maintenance products, with complete remote access capabilities.


Offshore:    Discharge Management, Process Improvement

Refineries:    Cooling Water, Waste Water Treatment

Industrial:    Lubricating and cooling oils contamination

Marine:    Bilge Water, Exhaust Gas Cleaning

Core Technology


• Aromatic hydrocarbon molecules are excited by the absorption of light.

• A Laser light source is used to excite the hydrocarbons in the oil molecules.

• A light detector is used to measure the fluorescence.


• Measurement of Total Suspended Solids.

• Sand management for water re-injection.

• Separator performance and optimisation.


• Ultrasonic cleaning of side stream and inline sensor heads.

• Sound wave is passed through the sapphire window.

• Creates cavitation on window surface jet washing the sensor head.
