Turner Designs Hydrocarbon Instruments

Oil in Water Monitoring and Measurement

Turner Designs Hydrocarbon Instruments, Inc. are specialists in the measurement and monitoring of oil in water. We are experts in the application of UV fluorescence technology to the monitoring of produced water and other oily wastewater. We provide state-of-the-art continuous on-line oil in water monitors as well as bench-top single sample analyzers. Instruments are listed as oil content monitors, oil in water monitors, oil in water analyzers, trace oil monitors and produced water monitors.

TD-500D portable oil in water meter

The TD-500D™ is a fluorometer designed for quick, easy and accurate measurements of crude oil and gas condensates in water. When properly calibrated with a correlation method or a known standard, the TD-500D can be used to determine concentrations of unknown samples. It features:

  • Oil and grease analysis in less than four minutes
  • Compatible with all popular extraction solvents
  • No solvent evaporation
  • Easy calibration with crude oil standards or correlation to other methods
  • Minimum detection limit <1ppm for most crude oils
  • Range 0ppm to >1,000ppm
  • Portable, hand held, <1lb
  • Measures WSOs at pH <2
  • No interference from methanol
  • Accurate and highly repeatable
  • Correlates to standard laboratory gravimetric and IR methods
  • CheckPOINT® solid calibration check standard
  • UV fluorescence technology

All Turner Designs instruments are manufactured under ISO 9001 certification.

Turner Designs' continuous on-line oil in water monitors are:

  • California EPA certified
  • USCG certified
  • IMO certified

TD-4100 XD oil content monitor

The TD-4100 XD General Purpose monitor is a lower cost version of the industry standard TD-4100 XD and is designed for general purpose areas (non-explosive atmospheres). It was designed for dirty water applications and uses our standard EZ Access Non-Contact Flowcell for lower maintenance. Field validation is via our CheckPOINT™ solid calibration check standard.

UV flouresence oil in water analyzers

The 4100 XD instruments use the principle of UV Fluorescence with high correlation to standard laboratory oil in water analysis methods. These rugged instruments are used in all industries offshore and onshore, from water purification to upstream and downstream oil industry applications. We provide worldwide field service for commissioning and training. For more technology information regarding oil measurement with UV Fluorescence, please visit our web site listed below.

Skid mounted oil in water monitor

The TD-4100 XD is a very simple self-contained skid mounted oil in water monitor ready to install on skid packages or directly on offshore facilities. No special pumps or mixers are required. Explosion proof options for North American and European standards as well as heaters and coolers allow it to be used on virtually any offshore or onshore oil production facility. Instruments are IMO and USCG certified and carry the CE Mark.

TD-107 for bilge water monitoring

The new TD-107™ uses our signature fluorescence measurement technology in a unique new package that can be universally applied to bilge water monitoring. Priced within range of standard light scatter type instruments, the TD-107 is low maintenance, rugged, and has all the features defined by marine customers and regulators including cell condition compensation up to 50% reduction in light transmission, at least 18 month internal permanent memory with data transfer via USB memory stick, 4mA-20mA output, and alarm relays.

Memory includes all events and a complete ppm vs time record. It is designed to interface directly with existing mounting for easy replacement of obsolete OCM technology. Turner Designs Hydrocarbon Instruments has teamed with NAG Marine of Norfolk, Virginia for exclusive worldwide sales and service for all bilge alarm applications.
