Remote Laser tunable diode laser methane natural gas leak detector
Principle of remote detection
LMS-Remote is based on the utilization of laser absorption spectrophotome-ter of methane gas for gas measurement.
The system detects natural gas leaks by emitting a laser at particular wave-length and analyzing the light reflection from an object to determine how much was absorbed by the methane in the natural gas.
The measured gas volume is expressed by methane column density (ppm - m): methane density (ppm) multiplied by thickness (m).
Explosion-proof certified detector
The LMS-Remote is GOST R approved applied for operation in hazardous are-as Zone 2.
LMS-Remote System can be fully integrated into existing struktures inclu-ding interaction with other systems such as fire protection systems, gas emission control systems.
LMS-Remote is a stationary natural gas leak detection system for remote monitoring of elevated methane gas concentrations in ambient air. It is specifically designed for the constant scanning and monitoring of mission-critical areas such as compressor stations, gas tanks, storage facilities, tank farms, gas stations and LNG Terminals.
The LMS-Remote System is based on new technology for detecting natural gas leaks. The system utilizes a post diode laser at a wavelength of 1.65 µm allowing the system to detect traced amount of gas concentra-tions. The optical unit is installed on a pan tilt platform and is designed to scan remote pre-set areas or pre-set target points. A laser beam is emitted from the sensor and strikes a remote object. The system analyces the laser light back scatter to determine how much, if any of the laser energy was absorbed by methane along the laser-light path. A unique detection algorithm allows for real-time measurement of the methane concentration above atmospheric levels. A video camera is installed in the detector helps the operator in determining the gas cloud location online.
The system consists of three components:
-> The optical unit is mounted on a new generation of servo driven pan/tilt head installed at an elevated location such as a facility mast lighting. This compoments contains the laser, receiving system, HD video camera, control board, heater, reference cell and signal processing board.
-> The electronic unit includes special instrumentations boxes with communication equipment and DC converter.
-> The operator PC constantly monitors detection alarms, system control, data, video storage and his tori- cal data analysis. The system continually records data including coordinates of leaks, sizes of leaks and
additional information about system operations. A report about system operations, leak sizes and loca- tions can be made using the included data-processing software.
Benefit of LMS-Remote
-> Fully automatic. The system can be programmed to scan specific areas.
-> Detects gas leaks faster than conventional methods. (detection speed 0.1 sec)
-> The LMS-Remote system operates 24 / 7 / 365.
-> The measured methane concentration is displayed in real time and stored for post analysis.
-> Sensitive only to methane. No false detections.
-> Panoramic scanning capabilities, no blind zones.
-> Can be fully integrated with existing facilities.
-> User-friendly software.
-> Complete monitoring include database of operation actions. Archive data for the entire period of operation.
-> Explosion-proof certificate.
-> Calibration and self-check during operation.
