THEORY OF OPERATION

Color variations in refined products indicate impurities and/or the presence of water. Refined products are often prone
to haze or diffused water contamination due to cooling towers which use water and in turn can saturate the product.
This can be a significant liability as color differentiation can be easily detected by the end user. The KAM
Colorimeter/Haze Analyzer is the ideal quantitative solution for monitoring both the color of refined products, including
dyed product, and the presence of haze (trace/dissolved water) in pipelines following the refining process. The KAM
CHA™ detects interface color variations within 1%, and unlike most colorimeters can detect the entire range of
visible color as defined by CIE 1931 (International Commission on Illumination). The simplicity of design and quality
of engineering employed in the Colorimeter/Haze Analyzer mean there are no moving parts. Using long-lasting LED
light sources ensures long-term, stable performance with limited maintenance and power requirements. In addition,
locating the electronics within an explosion-proof enclosure directly on the atmospheric end of the optical probe
creates a complete and compact unit with maximum installation flexibility. The KAM
other colorimeters, weighed down by large electronics/computer units, cannot.
The five LED sources (Red, Blue, Green, Yellow, and IR) send light via fiber optics to the sensor end inserted into the
pipeline or analyzer loop. These beams of light pass through a 25mm window of pipeline fluids and then are reflected
back through fiber optics to the electronics enclosure for a total path of 50mm. KAM uses four LED's for color
determination to increase the accuracy over three-color (RGB) models. The fifth (IR) LED provides haze detection.
