Arjay Engineering On-Line ppm Oil-in-Water HydroSense 2410

The HydroSense 2410 continuously monitors the water sample flowing through it for ppm concentrations of hydrocarbons. The display, signal output, and alarm can be configured within the 0-1000 ppm range. On-line monitoring for ppm concentrations of petroleum oils in effluent and produced water. The HydroSense 2410 is the engineered combination of three unique designs by Arjay. The sensing chamber contributes a continuous controlled water sample while the optical sensor package hovers above the passing stream. The Arjay controller then monitors the multiple signals to provide a reliable ppm concentration output. The HydroSense 2410 uses a UV fluorescence technique to target the aromatic component of the oil contamination. Through a site calibration, this aromatic tag provides an indication relative to total oil. A continuous sample flow is tapped or pumped off the process line and directed through the HydroSense chamber. It passes behind the non-contacting UV light source and is targeted with filtered light energy. 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. On the 2410-U, an ultrasonic module assists for cleaning and homogenizing the sample.
