Critical Pipeline Gas Leak Detector
Critical Pipeline Gas Leak Detector
Product Overview
The buried pipeline sentinel consists of an intelligent remote pipeline monitor, a new gas leak detection product developed based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). Designed for areas with unauthorized construction along the pipeline route and regions prone to micro-leaks in the network, it combines Narrowband IoT (NB-IoT/4G) technology with ultra-low-power circuit design. Installed via posts or surface mounting, it continuously monitors methane concentrations along the gas pipeline. Its vibration-based early warning system effectively detects potential pipe damage caused by irregular construction activities and unauthorized earth-moving operations nearby.
