enviroFlu Optical Oil in Water Meter
Brand: TriOS Optical SensorsenviroFlu is a new generation of high sensitive submersible sensors for oil-in-water measurement.
The used UV fluorescence principle for detection is much more sensitive than any other existing detection principle, like infrared scattering, etc.
This allows the detection of PAH traces in water down to single ppb levels (e.g. in drinking water or condensate applications).
Application areas include the petrochemical industry, leakage detection in cooling and wastewater streams as well as environmental monitoring.
The devices enable both stationary use in shafts, flows or piping, and mobile use through an optional hand-held measuring instrument.
An innovative coating reduces fouling of the optical measuring window and minimizes the maintenance.
Features- Operating principle: fluorescence
- Used for: PAH (polycyclic aromatic hydrocarbons) detection in water
- Typical applications are discharge monitoring of airports and factories, leakage detection and many others
- The sensors can be used either in stationary or portable applications
- A new innovative nano-coating on the lenses is preventing the optics from fouling and oil-films, making the enviroFlu-HC long term stable and virtually maintenance free
- In addition, the enviroFlu-HC can be used with an compressed air cleaning system. For a chemical-free check on location solid standards, so called SolidCALs, are available
- On request special application requirements can be met by changing the filter combinations, possible for example is an enviroFlu-BT for determination of BTX in water
- The enviroFlu-BT is also available in a deep sea version for operation in water depth down to 6,000 m (enviroFlu DS)
