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-line monitoring for ppm petroleum oil in industrial filtered water and cooling water

The HydroSense 3410 offers a high accuracy approach to monitoring low concentrations of free and soluble oils in water. Combining many unique design features into a compact package makes this an ideal solution to monitoring for oil contamination in your water system.

 

The HydroSense 3410 uses a UV fluorescence technique to target the aromatic component of the oil contamination. Through a site calibration this aromatic tag is able to provide an indication relative to total oil.

 

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, filtered UV light is targeted in the water. 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.

Continuous monitoring of separated oil thickness on a water surface

The 4100-HCF monitors a floating sensor on the water surface to indicate the thickness of separated oil. An LCD display of the thickness, analog output and relay alarms are standard.

 

The 4100-HCF float sensor monitors the capacitance field of the water surface. As the oil accumulates on the surface, the sensor capacitance changes. This interface signal is used to provide outputs, displays and relay control.

Continuous monitoring for % concentration of water in oil emulsions

The 4100-OWM is used for monitoring as the water phase changes to oil in a tank or pipe. A probe inserted into a tank or pipe measures the capacitance field. This is ideal for general monitoring of oils and other liquid phase changes in a process.

 

The 4100-OWM sensing probe monitors the capacitance field around the probe within a concentric shield, tank or pipe. The emulsion characteristics of water to oil is not strictly linear and the Arjay controller allows for a 5 point calibration to enhance accuracy over an extended range. This instrument is ideal for general monitoring and trending of process conditions.
