Principle of measurement
Laser Methane is based on utilization of laser absorption spectrophotometer of methane gas for gas measurement. The system detects natural gas leaks by emitting a Laser at particular wavelengths and analyzing the light reflected back from the ground to determine how much was absorbed by the methane in the natural gas. The measured gas volume is expressed by the methane column density (ppm-m):
methane density (ppm) multiplied by the thickness (m)Difficult to reach areas
Accumulated gas clouds in commercial and industrial facilities are commonplace. The Laser Methane mini allows for detection removing the need for ladders, scaffolding or aerial platforms.Additional technology features
-> Can detect faster than conventional method (Detection speed 0.1 sec).
-> Remote Detection
-> By simply pointing the laser beam towards the suspected leak or along the survey line.
-> Can detect through the window. Measurement of room filled with methane from outside.
-> Only sensitive to methane. No false reports.Typical applications include
-> Emergency response
-> Industrial and commercial property surveys
-> Gas processing plant
-> Landfield monitoring
-> Distribution pipeline surveys
-> Transmission pipeline surveys
-> Refinery surveys
Methane (CH4) & methane-containing gasses
Interaction with Android mobile devices
-> Bluetooth communication
-> Realtime data display (measuring results)
-> GPS data tracking
-> Data storage for tranceability
-> Capability to add pictures
-> Email data transfer
A new era in portable methane detection has arrived. Truly portable and handheld, the Laser Methane Detector (LMD) and Laser Methane mini (LMm) offers users the ability to detect methane remotely. What once was a time consuming and resource draining procedure can now be completed in a fraction of the time by utilizing the best in Tunable Diode Laser Absorption Spectroscopy (TDLAS).
Current methods such as FID, require users to be within arm’s reach of a potential methane source, and to position the detector into the gas cloud, often requiring scaﬀ olding or special access equipment to reach the area of interest. In stark contrast, the Laser Methane handhelds only need the emitted beam to pass through the gas cloud in order to detect methane. By simply pointing the laser beam towards a suspected leak, or along a survey line the handheld detector will monitor the level if methane detected.
Escaping gas carries with it a risk to the surveyor detecting the leak. Remote detection of methane enables the surveyor to operate a potential danger zone. Removing the surveyor from hazardous and hard to reach areas, reduces the risk of injury.
