Arjay Engineering On-Line ppm Oil-in-Water HydroSense 4420

The HydroSense 4420-OCM continuously monitors a clean water sample for oil leaks. The display, signal output, and alarm can be configured within the 0-250 ppm range. On-line alarm for oil presence in filtered effluent and cooling water The HydroSense 4420-OCM offers a low-cost approach to monitoring ppm concentrations of emulsified free oils in clean water. Combining many unique design features into a compact package makes this an ideal solution to monitoring for oil leaks in your water system. The HydroSense 4420-OCM uses a light scatter technique to respond to oil contamination in the water. A slip stream approach directs a continuous sample flow through the HydroSense unit and back into the process stream. While it passes through the sample cell a controlled light source is directed into the water. The emulsified oils in the water will scatter the light toward the light sensors placed strategically around the cell. The intensity of light energy is measured to provide an indication of the ppm concentration.
