The INVALCO HSS 1016 has been designed for municipal and industrial applications to measure PPM levels of hydrocarbons in aqueous solutions. Typical applications include PPM trace amounts of oil in effluent water from storm water runoff, oil in cooling water, produced water, and oil/water separators. Other measurements and mediums can be monitored on request (i.e. colorants in fluids, etc.).
The INVALCO HSS 1016 uses a UV fluorescence technique to target the aromatic component of the oil contamination. Through a site calibration this aromatic tag is able to provide an indication relative to total oil.
A slip stream approach directs a continuous sample flow through the Hydro Surveillance System and back into the process stream. While it passes through the sample cell, filtered UV light is targeted in the water. The soluble and emulsified oils in the water will excite from this light energy and fluoresce light energy back out of the water at a signature wavelength. The intensity of light energy at this wavelength is measured to provide an indication of the ppm concentration.
Features and Benefits
- Ultrasonic disc generates a continuous cleaning action within the sample cell to reduce maintenance frequency
- Compensation for temperature and lamp deterioration minimizes recalibration requirements
- Long life lamp
- Desiccant chamber keeps electronics dry in humid conditions
- Continuous display updates every one second
- No consumables or chemical used
- Sample flow returns to the process
- Sample cell can be exchanged with prepared samples for easy testing and calibration
- No tools necessary for routine maintenance
Performance
The performance is based on the site calibration to a known hydrocarbon concentration in stable background water. Changes in hydrocarbon make-up and background stability may affect the output. Through a simple calibration, this unit correlates well with laboratory ISO and EPA methods.
