Online UV Fluorescence Oil In Water Sensor
Detection method:
Online oil in water sensor, Commonly used oil-in-water detection methods are suspension method (D/λ<=1), infrared spectrophotometry (not suitable for low range), and ultraviolet spectrophotometry (not suitable for high range).
Features of Online oil-in-water sensor:
Using the principle of fluorescence. Compared with several commonly used methods, the fluorescence method is more efficient, faster, and can be monitored online in real time.
- Digital sensor, RS-485 output, supports MODBUS.
- Withan automatic cleaning brush to eliminate the impact of oil on the measurement.
- Eliminate the effects of ambient light on measurements with unique optical and electronic filtering techniques.
- Unaffected by suspended solids in water.

Advantage:
The oil in water sensor has better repeatability and stability. The use of self-cleaning brushes can eliminate air bubbles, reduce the influence of pollution on the measurement, make the maintenance cycle longer, and maintain excellent stability for long-term online use. It can play an early warning role in oil pollution in water.
Installation Case:
It is suitable for water quality monitoring scenarios such as oil quality monitoring, industrial circulating water, condensate water, wastewater treatment, and surface water stations.
