HydroSense 4410-LMP Continuous Non-Contacting for Ordinary Locations
The HydroSense 4410-LMP offers continuous on-line monitoring for ppm concentrations of petroleum oils in effluent and produced water without chemicals or lag time. A non-contacting sensor design minimizes system maintenance. The 4410-LMP is the engineered combination of three unique designs:

  • The sensing chamber contributres a continuous controlled water sample
  • While the optical sensor package hovers above the passing strean
  • The Arjay controller then monitors the multiple signals to provide a reliable ppm concentration output 

The HydroSense 4410-LMP 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 noncontacting 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.

Features & Benefits:

• Special UV absorbing flow plate sheens the water over a large surface area. The resulting high surface area to depth ratio provides many benefits.
• Sensitivity to oil molecules is increased by maximizing the optical viewing area.
• Minimal depth discourages oil molecules from ‘hiding’ behind particulates in the water.
• Large lamp source targets the water from multiple angles to get a representative sampling of all oil.
• Large sample target area ensures a representative and stable snapshot of the water conditions.
• The unit can tolerate suspended solids up to 400 mg/l.
• Non-contacting optics minimizes maintenance.
• Compensation for temperature and lamp degradation minimizes recalibration requirements.
• Alarm warns of impending lamp replacement.
• Long life lamp expectancy of 18 months.
• Continuous on-line monitoring reads the water 50 times/second with an averaged display update every one second.
• No consumables or chemical used.
• Sample flow gravity outfalls to drain.
• Designed for harsh environments with a 316 SS housing.
• No tools necessary for routine maintenance or lamp replacement.
• The flow or power does not require to be turned off during routine maintenance.
• Flow chamber diversion system conditions and clarifies sample.
• Multi-point calibration available to customize response curves.
