LMC series Detectors of leak of methane

LMC G2 DL for DJI Matrice M600

On June 24, 2019 it became known that the company Pergamum together with software developer SPH Engineering (Latvia) and IT- the company "Croc" provided the second generation of a pilotless system for leak detection of methane (CH4) based on drone DJI Matrice 600. The complex is intended for inspection of various technology platforms (GRS, UGS, LNG and GPP) and tankers.

Earlier Pergamum had a methane detector for the LMC drone with data writing onboard, but without a possibility of online data transmission on the earth and their displays on the operator console. Croc implemented transfer on the earth on the hardware-software complex. As envisioned by the companies, it will allow to react on site to the fact of detection of leak and to take measures for exact localization and elimination and also to change a flight task and to make repeated run for leak confirmation.

Customers said that it is inconvenient to them to obtain data after they landed, they need to receive them instantly to understand what occurs — the head of department of developments and production Pergamum Engineering Semyon Neverov specified.[1]

Croc and the Latvian SPH Engineering developed software for LMC G2 DL which creates a flight task, a flight trajectory, monitors in real time a situation on an object, obtains and processes data from the methane detector. In the software it is also possible to enter objects to library: consumers do not need to build every time a flight task — it can be selected from library.

LMC G2 DL inspects vulgar objects (for example, gas distribution points) with a speed up to 100 sq.m in 5 minutes. In one day it is possible to inspect 4-5 GRP at distance of 5-10 km from each other. LMC G2 DL flies at the height of 100 meters (optimal — 30 m), speed — 100 km/h. The complex is unrolled in 10 minutes. It can work in temperature condition from -10 ° up to +40 °C, i.e. does not fly in the winter. 1.7 kg weigh, eat from UAV batteries.

Data transmission about the found leaks on the control panel of the pilot in real time (Downlink) takes place under the DJI protocol. Data transmission distance — up to 5 km. According to developers, it allows:

• 1) to react on site to the fact of detection of leak and to take measures for exact localization and elimination;
• 2) change a flight task and make repeated run for leak confirmation.

Distinctive features of LMC G2 DL:

• Sensitivity — 1... 50.000 ppm×m;
• Flight altitude — up to 30 m;
• Flight time — up to 25 minutes;
• Inspection with a speed of 100 sq.m in 5 minutes;
• Online data transmission under the standard DJI protocol;
• Data transmission distance — up to 5 km;
• 3D maps allow to consider a land relief by preparation of a flight task;
• Possibility of direct control of a system with PDU;
• Convenience of transportation;
• Simplicity of deployment and management.

Development can be applied for:

• inspections of gas pipelines;
• survey of tanks;
• monitoring of emissions on landfills;
• tests of gas wells;
• security audit at the plants, etc.

LMC for the UAV

Upon the demand of the customer the Pergamum company released three versions of the UAV with remote the laser detector of methane, the tasks of leak detection of methane covering all range from air. All solutions of Pergamum company have an opportunity both automatic (on GPS coordinates), and manual control by flight.

According to information for June, 2019 the detector of LMC methane is equipped by a logger and the GPS tracker. It is delivered with the Russian geksakopter of Supercam X6M2. The flash memory writes on removable all your flights and coordinates of the found leaks. The complex is intended for inspection of various technology platforms (GRS, UGS, LNG and GPP) and tankers.

The UAV equipped with these the device, sensitive to methane, defines the increased concentration of gas at different distances from leak sources. The sensitivity of the device allows to configure measurements of leaks at distance of 30, 50 and 100 meters. The detector is universal, it can be removed from a kopter and to apply to inspectors as the manual device to search of leak of natural gas. All portable detectors of methane delivered Pergamum can be installed practically on any pilotless devices.

2017: Transfer of a metanoiskatel on the pilotless drone

In 2017 Pergamum was reduced in sizes by a metanoiskatel and transferred it to the pilotless drone — it gave noticeable economy. So, according to the company, flight hour of MI-8 with the detector is installed about 120 thousand rubles, flight hour on the DJI M drone of 600 — 12.5 thousand rubles.
