LMS systems advantages
Ideal solutions for areal facilities and tanks
24/7 control
The LMS / LMS Open-Path systems are designed to provide continuous monitoring of the methane level in the surrounding atmosphere. It can control any territory in a fully autonomous mode.
Smart scan
With LMS, you can pre-program the scan route by key points at the facility. This completely eliminates the situation where important infrastructure facilities do not fall into the control zone.
Perimeter control
The LMS Open-Path cost-efficiently offers true continuous methane emissions monitoring that is independent of wind direction by reflecting the laser around the perimeter of the gas facility.
Protection
All external units of the LMS / LMS Open-Path systems are protected against dust and water. This eliminates possible influence of external weather factors (rain, snow, sandstorm) on the system.
LMS
The area is scanned automatically with a programmed path. The system operator can see the facility scanning process on the monitor at the control panel visually in real time.
If a leak is detected along the scanning laser path, the system records this fact, gas concentration at the leak, leak coordinates and time.

LMS Open-Path
The remote gas analyzer is designed to detect methane in the atmospheric air and automatically signal the excess of its concentration. The device measures the intensity of infrared radiation when it passes through an environment in which methane vapor is present. Unlike similar gas analyzers made using open optical path technology, in the Open Path Gas Detector both the transmitter and the infrared receiver are installed in one unit, and a retroreflector is used to reflect the signal.

FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.
Laser radiation is completely safe, it corresponds to class 3R.
Yes, the instrument works in all weather conditions.
No. The detector contains a reference cell with methane inside and calibration is performed at each start-up and during operation.
It works remotely. There is no direct contact with the hazardous environment.
Direct range of the LMS laser detector is 150 meters; 60 meters for LMS mini. This distance can be increased using special repeaters to 1,000 meters and 600 meters respectively.
Yes, because glass allows the transmission of infrared radiation.
LMS mini is ATEX and IECex certified. LMS is only available in a conventional enclosure without explosion protection.
