July 29 Anping County, Hengshui, China (Reuters)-two people were killed and two were seriously injured in an explosion at a street shop in the county at 10:13 am, the explosion occurred in the jacking natural gas pipeline during the reconstruction of the secondary pipe network of the water supply company.

As the“Lifeline” of the city underground, the on-line monitoring and early warning of gas pipeline leakage is an important part of the city infrastructure, which can avoid the accident caused by the failure of micro-leakage detection in time.

Passive fiber laser leakage monitoring system

Preventive monitoring

Each monitoring channel response time only 10 seconds, transmission distance up to 20 km. PPM level can accurately detect trace gas leakage, real gas leakage preventive monitoring.

No power supply on site, the system is more secure

The monitoring site does not need power supply and is connected by optical fiber. The monitoring platform can receive and process the information of each photosensitive terminal in real time, and the monitoring is more stable.

Easy installation and more flexible configuration

It overturns the traditional system composition mode, and adopts the digital design from the photosensitive terminal to the control system. The simplified system structure makes the installation easier and can satisfy more application requirements of customers.

Detect gas diversity

With methane, ethylene, acetylene and other gas detection capabilities (according to customer demand to provide more gas detection program) .
