Overview
OPS DS530 Online Oil in Water Sensor is a complete solution for oil in water measurements in the waste water. The oil in water sensor adopts the principle of ultraviolet fluorescence analysis, has high sensitivity, and can detect soluble and emulsifiable oils. In addition, the self-cleaning brush version can be selected to effectively eliminate the influence of oil pollution on the measurement. It is suitable for a variety of water quality measurement scenarios such as oilfield monitoring, industrial circulating water, condensate, wastewater treatment, and surface water stations.
Measuring Principle of DS530 Fluorescence Oil in Water Sensor
The ultraviolet fluorescence method is used to monitor the concentration of oil in the water, and the oil concentration in the water is quantitatively analyzed based on the fluorescence intensity emitted by the petroleum and its aromatic hydrocarbon compounds and compounds containing conjugated double bonds after absorbing ultraviolet light. The aromatic hydrocarbons in petroleum can produce fluorescence under the excitation of ultraviolet light, and the value of oil in water can be calculated according to the intensity of the fluorescence.

FAQs
1. How does an online oil-in-water sensor work?
For Fluorescence-based oil in water sensors: These sensors utilize fluorescent molecules that emit light when excited by a specific wavelength of light. When oil or hydrocarbons are present in water, they interact with the fluorescent molecules, causing a change in the emitted light’s intensity or wavelength. By measuring this change, the sensor can determine the oil concentration in the water.
The sensor typically consists of a probe or sensor head that is immersed in the water sample. This probe contains the necessary components for detecting and measuring the presence of oil. The data collected by the sensor can then be analyzed to determine the oil concentration in the water.
2. Why do we need to monitor oil in water?
Oils and hydrocarbons are often a major component of a variety of products, from fuels to solvents to the many chemicals used in industry during processing. In industrial production, some of these hydrocarbons, oils, and solvents can leak into sewers or, worse, directly into the environment. Similarly, domestic and agricultural fuel storage can lead to accidental spills into waterways and aquifers. In the oil industry, one ton of oil spilled can quickly spread over an oil slick covering an area of approximately 10,000 sq. m. Oil in water sensors and analyzers can be useful by giving early warning of problems as they occur.
