Natural Gas Safety Monitoring System

System Introduction

The NGSM System is composed of laser methane detection equipment, control cabinet and system software, among which the laser methane detection equipment is the core equipment of the NGSM System. The product is designed based on TDLAS laser gas detection technology, and the absorption amount of light molecule gas of specific wavelength is analyzed and calculated by harmonic algorithm, so as to realize long-distance and non-contact methane gas detection. The NGSM System can realize real-time monitoring and early warning of natural gas leakage disasters and realize 7×24 hours unattended, which can not only improve the inspection efficiency, reduce the pipeline monitoring cost, but also avoid the safety risks caused by human negligence and error. Once the production unit leaks, on-site personnel can obtain relevant information in the first time. Implement security measures and emergency plans in a timely manner. The following shows the system topology.
