LMS advantages
Ideal solution for areal facilities
24/7 control
The LMS system is 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.
Rain and dust protection
All external units of the LMS systems are protected against dust and water. This eliminates possible influence of external weather factors (rain, snow, sandstorm) on the system.
How It Works?
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.
System behavior at the time of leak detection can also be programmed — record data and continue scanning, send a message to the duty control panel, or stop scanning and turn on the alarm. These actions can vary depending on the threshold leakage concentration.

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, there is no impact.
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 492 feet (150 meters); 196 feet (60 meters) for LMS mini. This distance can be increased using special repeaters to 1093 yards (1,000 meters) and 656 yards (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.
