OID Optical Interface Detector

Overview

OID™ FT Flow Through model

The KAM OID Optical Interface Detector has been the preferred sensor for interface detection between refined products since its inception in 2000. Like eyes in the pipe, it provides accurate, real-time data on product interface even when density does not change between products such as with multiple grades of diesel, allowing operators to make cuts with confidence and significantly reduce product downgrade and/or transmix.

Fiber optics within the patented optical probe respond to the absorption, fluorescence, and refractive properties of the fluid, and the combined return signal is then turned into an “optical signature,” recognizing qualitative changes in pipeline fluids.

The OID is designed for minimal maintenance and ongoing ease of use. Long-lasting LED light sources ensure long-term, stable performance and minimal power consumption. All electronics are located in an explosion-proof enclosure directly on the end of the probe for  a complete and compact unit with maximum installation flexibility.

Measurement is completely automatic and the output signal can be sent to the SCADA, PLC’s, or to a Central Control Room.

HOW IT WORKS

  • Patented optical probe utilizes optimal wavelength for interface detection
  • Measures the absorption, fluorescence, and refractive properties of the fluid
  • Combined fluid properties are output as an analog signal or “optical signature” unique to each product
  • Output signal can be sent to the SCADA, PLC’s, or to a Central Control Room
  • Measurement is fully automatic

KEY ADVANTAGES

  • Detects the interface of specialty fuels such as ULSD (Ultra-Low Sulfur Diesel)
  • Lenses do not require cleaning
  • Electronics are housed directly on the atmospheric end of the probe
  • No moving parts
  • Insertable model installs without having to drain the pipe
  • Uses LED’s for long-term performance with minimal power and maintenance requirements

APPLICATIONS

  • Batching
  • Interface detection
  • Product transmix management
  • Product downgrade management
  • Pipeline automation
  • Chemicals interface
  • Clear oil interface
  • Quality control
