• Differential light absorption unaffected by opacity
• Single unit installation – no separate safe area controller required
• ATEX certified for hazardous area installation

Typical applications
• Fuel monitoring
Transportation fuels may be coloured to ensure they are allocated correctly. Mistakes, such as putting the wrong fuel into a tank, can therefore be avoided.
• Dying of gas oil
The same fuel can be taxed by governments at different levels depending on their application, so different coloured dyes are used to distinguish them.
• On-line blending
Model 7613 can be used to check the colour of a product during blending.
• Interface detection
Liquids of very similar density, alternately using a common pipeline, can be identified and directed to the correct storage tank.
• Oil heat exchanger breakthrough
