Usable with large water level fluctuation
The laser scanning will detect oil on water surfaces between 30 cm and 3 m from the detector, enabling use where there are surface waves or water level fluctuations.
Avoiding false alarms
False alarms due to waves or reflective floating matter can be avoided by adjusting the continuous detection time.
Resistance to interference from ambient light
Modulated light and a band-pass optical filter are used to eliminate interference from sunlight and other ambient.
In addition to detection of a film of oil or other liquid on water surfaces, the unit may be used for detection of oil, water, or other liquid on dry surfaces.
Easy to maintain
No adjustment necessary when the scanner unit is replaced.
Easy to install
The optical module is emplaced on a free-hanging assembly so that it corrects itself the optical axis to true vertical and does not require realignment if the unit shifts after installation.
