How it worksGreenMon

The GreenMon oil content monitor is based on Raman scattering and fluorescencespectroscopy of a free falling sample water jet. The use of these technologiesenables accurate oil content monitoring of high turbidity muddy waters without theneed for frequent recalibration or zero point check with clean water. The free fallingsample water jet means that there’s no sensor glass fouling or scaling demandingfrequent cleaning. This makes the GreenMon ideal for demanding 24/7 applications.

The GreenMon oil content monitor separately indicates the contents of aromatichydrocarbons, CH stretch hydrocarbons, total hydrocarbons, turbidity, andtemperature. The GreenMon logs the readings in its memory, and the local displaycan be set to indicate the readings numerically or as a graph. High ingressprotection, corrosion resistant materials, and data connection to the process controlmakes the GreenMon ideal for offshore as well as land based industrial applications.
