HZ0103005
HZ-WL-15A Natural Gas Well Gas Leak Acoustic Fingerprint Intelligent Monitoring Device is an edge‑computing acoustic monitor designed by HERTZINNO for wellheads and high‑pressure natural gas pipelines. Its core technology path is acoustic fingerprint recognition + edge computing. Equipped with an embedded deep learning algorithm chip, it performs AI inference directly on the device without relying on cloud connectivity.
The device integrates a 9‑channel MEMS acoustic sensor array with a frequency response range of 20Hz – 80kHz, capable of capturing the turbulent noise and pipe wall stress waves generated by high‑pressure gas jets. It automatically filters out environmental interference such as wind, rain, and vehicle sounds, accurately extracting the unique acoustic fingerprint of gas leaks.
The main unit features an aluminum alloy enclosure with IP51 protection and Ex ib IIC T6 Gb intrinsically safe explosion‑proof certification. Operating temperature range is -30°C to +60°C, suitable for harsh outdoor environments. It supports 4G (full network compatibility) and Ethernet communication, with onboard 32GB storage (expandable up to 2TB). Standard industrial protocols (HTTP, Modbus TCP) enable seamless integration into existing monitoring platforms or SCADA systems.
Typical applications:
Real‑time gas leak warning at natural gas wellheads
Unattended monitoring of flanges and valves on high‑pressure pipelines
24/7 intelligent inspection of remote well sites
HZ-WL-15A upgrades leak detection from “periodic manual patrol” to proactive intelligent listening, significantly reducing false alarm rates and improving safety and operational reliability at oil & gas facilities.
