Product Description
WL139 Smart Gas Monitoring Device forGas Pipeline Networks
Product Introduction
The WL139 Smart Gas Network Monitoring Device is a new generationspecialized gas detector developed by our company, primarily designed forpipeline networks, underground pipe wells, gas pressure regulationcabinets/cubicles, and urban underground utility tunnels. It supports installationvia buried posts or wall-mounting in underground wells to accommodatediverse monitoring requirements.Beyond periodic combustible gas concentration detection and leakage early warning capabilities, it incorporates avibration monitoring module (sensitively detecting abnormal vibrations fromthird-party construction activities), along with a water submersion alarm deviceand optional well cover anomaly detection. All monitoring data is periodicallyuploaded to the cloud platform via wireless networks, enabling intelligent early warning and risk prevention and control.
