OilWatcher Operational Tutorials
Initial Settings
Measurement Principles
-
Fluorescence for 0.1-500 ppm
-
Light Absorption for concentrations >500 ppm
-
Automatic selection of measurement principle
-
Ability to calibrate to high solids/changing water color in different produced water sources
-
2 sensors in 1!
Measurement Details
Fluorescence is the most widely accepted method for oil-in-water concentration measurements. By combining this technique with light absorption, and with the use of our unique algorithm, the OilWatcher's range of detectable hydrocarbon concentrations is greatly expanded! This dual-modal imaging technique also provides the ability to accurately detect spikes with high reliability.
Applications
-
Production: Monitoring process water, chemical effectiveness, produced water discharge and reinjection, separator and filter functionality, refinery separation and discharge water quality
-
Salt Water Disposal: Monitoring oil-in-water concentrations to improve skim oil revenue, and alert operators on high reading to ensure injection equipment is protected from high oil-in-water content
-
Other: metalworking cooling water for casting and hot rolling to detect leaks in hydraulic or lubricant oil, food oils concentration from ppm to 100%, municipal water intake with oil (from refineries in particular), airport runoff

Functional Details
The 4 OilWatcher configurations provide
flexibility to measure oil concentrations in a variety of oily water applications. Data acquisition of concentration trends over an extended period of time give the user valuable knowledge about their produced or process water, its impact on equipment, and the potential for increased revenue from oil capture.
Measurement Configurations
-
Low Concentrations: 0.1 - 20 ppm
-
Ideal for filtration applications in order to monitor filter effectiveness and alert the user when breakthrough occurs
-
-
Medium Concentrations: 1 - 500 ppm
-
A wide variety of applications with low oil-in-water concentrations, and the potential for spikes to occur.
-
Perfect for discharge, disposal, and reinjection applications.
-
-
High Concentrations: 10 - 5000 ppm
-
Useful for any oily water application that has the potential for large upsets.
-
-
Free Oil: 0.5% - 10% free oil in water
