HSS 1026 Hydro Surveillance System

The INVALCO HSS 1026 oil in Water monitor has been designed for municipal and industrial applications to measure PPM levels of hydrocarbons in aqueous solutions. Typical applications include PPM trace amounts of oil in effluent water from storm water runoff, oil in cooling water, produced water, and oil/water separators. Other measurements and mediums can be monitored on request (i. e. colorants in fluids, etc.).

A continuous sample is directed into the cuvette using a pumped or process pressure source. A minimal flow rate is required. The sample is released from the cuvette by a gravity flow to a drain or sump.

The INVALCO HSS 1026 uses a light scatter technique to respond to oil contamination in the water. A slip stream approach directs a continuous sample flow through the Hydro Surveillance System 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.


Features and Benefits
