LaserGasPatroller LGP 800

Product catalog summary

Overview
The LaserGasPatroller LGP 800 is a vehicle-based solution designed for the economical and automatic inspection of underground gas pipes. It utilizes a laser-based measuring system to detect gas leaks as the vehicle drives over the pipes, operated by the SeCuRi® SAT software system.

Principle of Operation
The system detects natural gas (methane) leaks by drawing in samples through bell probes as the vehicle moves. The LGP 800 uses Tunable Diode Laser Spectroscopy (TDLS) to measure methane concentration, ensuring no interference from other gases.

Measurement Unit - LGP 800
The LGP 800 is compact and can be mounted anywhere in the vehicle. It is optimized for low power consumption, allowing operation from a standard car battery. The system includes three external outputs for additional alerts like sirens or lights.

Gas Sample Module
The module uses eight bell probes to draw in gas samples efficiently, which are then analyzed by the LGP 800.

PC Control Unit – SeCuRi® SAT
The LGP 800 connects via Bluetooth to a Windows device running SeCuRi® SAT software, which controls the system and documents inspections. It records data such as GPS location, time, and gas values, and can export data in KML format for use with GIS systems.

GPS System with Dead Reckoning
The integrated GPS system includes dead reckoning support to maintain accurate positioning even when GPS signals are lost.

Upgrade and Compatibility
The LGP 800 can replace existing Leakplotter modules, offering plug-and-play compatibility and multilingual support.

LaserGasPatroller LGP 800 – economical – laser-based The LaserGasPatroller is a vehicle-based solution for the economical network inspection of underground gas pipes. Gas leaks are detected when the laser-based measuring system LGP 800 is driven over the gas pipes. The LGP 800 is operated by the SeCuRi® SAT software system. SeCuRi® SAT is the world‘s most sophisticated documentation system for pipe network inspection. Principle Natural gas (methane CH4) is a light gas which escapes from a leak in a gas pipe and diffuses through the soil to the road surface. As the LaserGasPatroller drives over...

– fully automatic SeCuRi® SAT includes versatile recording tools for documenting advanced tasks in addition to the pipe network inspection. For example, structures or planting encroaching on the course of the pipe network can be recorded by means of the Defect button. The software also includes a powerful print and export function. The recorded data and map material can be exported in KML file format for Google Earth, for example. Damage button GPS system with dead reckoning The LGP 800 has an integrated GPS system with dead reckoning support. If the GPS signal is lost because of a high building...
