FPI’s Single Gas Analyzer

InSitu Gas CEMS

System Features:

  • No cross-interference
  • Fast response, less than 1 second
  • Diverse optical length (0.5-20m)
  • Install base of over 8000 instruments worldwide
  • International ATEX Certified.

FPI’s Single Gas Analyser (LGA) utilises Tunable Diode Laser Absorbtion Spectroscopy (TDLAS). The LGA System can accurately measure in harsh environments and is virtually maintenance free.

Direct Extractive & Dilution Extractive Continuous Gas Analyser Systems

  • Turnkey gas monitoring systems for process and emission monitoring
  • Custom design to suit your site requirements
  • Reputation for quality systems that hold up in harsh environments, including corrosive gases such as TRS & H2S Applications
  • Locally integrated and supported

Dilution Extraction Systems utilise an eductor-style dilution probe, non-heated sample line and Teledyne API or Tiger Optics Ambient analysers, proving accurate stack gas measurements while minimising maintenance in corrosive environments.

Direct Extraction Systems offer a simple, economical option utilising heated probe, heated sample line, sample conditioning system, probe blow back (if required) and Teledyne API Medium and High Level analyser.

Gasmet FTIR analysers are also available for mutli-gas analysis.

Insitu Dust/Opacity Analysers

TES partner with various suppliers of reliable Dust and Opacity Monitors. Including:

Opacity Monitors

  • to meet US EPA PS 1 or TUV requirements

Laser Dust Monitor

  • Low maintenance, low calibration requirements, economical option
  • mg/m3 or Opacity output

Triboelectric Bag Leak and Dust Monitor

  • Bag leak detectors and solids flow monitors to monitor and measure dust, powders, and bulk solids for environmental and process control applications.

Insitu Flow/Velocity Sensors

TES offer Pitot Tube, Ultrasonic and Optical Flow Sensor technologies for Flow/Velocity Monitoring.

The Optical Flow Sensor (OFS) manufactured by OSI is a continuous flow measurement system for small and large stacks and ducts.

Advantages of Optical Scintillation flow measurement include:

  • Temperature, pressure and humidity have no impact on the measurement
  • Instrumentation is installed at a 90° angle to the gas flow, needing only one platform to access, rather than potentially two on smaller stacks
  • It is a true non-contact instrument – nothing protrudes into the stack. The instrument is very rugged, they are even installed in flare stacks! And normally there is no need for blowers unless it is a really dirty application.
  • Measurements are drift free
  • Measurement is across the entire stack (rather than one point when a pitot is used)
  • Path length and opacity do not affect the measurement
  • Compliant with US EPA 40CFR 60 and 75
  • Very low maintenance and ongoing cost of ownership (no consumables).
