What you need

HOW IT WORKS

  • Boreal’s TDLAS technology counts every target gas molecule in the measurement path to give a path integrated ppm-m concentration

  • This analyzer utilizes a mono-static configuration with the analyzer being a transceiver and having a passive retro-reflector returning the laser light
  • A tilt-pan scanner can be utilized to enable one analyzer to monitor multiple paths

Retro-Reflectors

  • Boreal Laser utilizes a mono-static configuration with the analyzer being a transceiver and having a passive retro-reflector returning the laser light
  • The distance between the transceiver and the retro-reflector forms the physical path length and active measurement path
  • Reflected light returns in the same direction as the incident light and the beam is reflected 180 degrees
  • A retro is like a section through a corner and has three faces that form the inside corner of a cube
  • If the location is outside and in a humid climate, a rain hood and some heating in the enclosure may be necessary to prevent condensation on the window
  • The retros can tolerate small vibrations and movement so the retro mounting does not need to be as robust as the mounting for the analyzer

PROGRAMMABLE TILT-PAN SCANNER

  • Allows a single analyzer or measurement head to monitor multiple paths by aiming at different successive retro-reflectors
  • Can provide a way to remotely optimize the alignment
  • The programmable tilt-pan scanner is controlled by Boreal’s GasView-MP software.
  • The scanner can either be mounted on a heavy-duty tripod for temporary/portable applications or affixed to a structure for permanent installations.
  • The scanner and analyzer can be communicated with remotely using Boreal’s Remote Monitoring + Control Centre

RESPONSE CELL

  • To validate that the GasFinder3-OP is responding appropriately to the target gasa response cell can be inserted into the active measurement path
  • While the GasFinder3-OP is designed to report any instrument or measurement errors, this response test mitigates the small remaining risk of an instrument in an unreported error condition
  • The response cell is NOT a field calibration
  • Depending on how the response cell is held in the active measurement path the path length can change and therefore so will the indicated reading and one cannot expect identical readings from the response cell every time it is put into the path

Remote Monitoring + Control Centre

  • The remote monitoring + control centre is utilized to power, log data, and allow remote communication (read & write) to provide on-board intelligence for applicable components:
    • Interface software for the GasFinder (GasViewMP)
    • Weather data (3D sonic anemometer + met station)
    • Interface software for Tilt-Pan Scanner (GasViewMP)
    • Relays (can be used to remotely cycle the power)
    • Webcam (useful tool for verifying weather conditions)
    • Measurement campaigns can now be monitored remotely without having to physically visit the installation
    • Depending on the accessories the operator can remotely intervene with the installation if necessary
