Commonly used oil in water detection methods include suspension method
(D/λ<=1), infrared spectrophotometry (not suitable for low range), and
ultraviolet spectrophotometry (not suitable for high range). Our online oil in
water sensor uses the principle of fluorescence. Compared with several
commonly used methods, the fluorescence method is more efficient and
quicker, and can be monitored online in real time. The sensor has better
repeatability and stability. Self-cleaning brush can be used to eliminate air
bubbles, reduce the impact of contamination on the measurement, make the
maintenance cycle longer, and maintain excellent stability for long-term online
use. It can play an early warning role on oil pollution in water. Suitable for oil
quality monitoring, industrial circulating water, condensate, wastewater
treatment, surface water stations and other water quality monitoring
scenarios.
Principle
The oil content in the water was monitored by ultraviolet fluorescence method, and the
concentration of oil in the water was quantitatively analyzed according to the fluorescence
intensity of the oil and its aromatic hydrocarbon compound and the conjugated double
bond compound absorbing ultraviolet light. The aromatic hydrocarbons in petroleum can
generate fluorescence under the excitation of ultraviolet light, and calculate the value of oil
in water according to the intensity of fluorescence.
