RECOMMENDATION丨GF370 GIMBAL-MOUNTED LASER METHANE REMOTE

DETECTOR

DEVELOPMENT BACKGROUND

According to statistics, urban gas safety incidents have become the third leading cause of accidents in China, following traffic and workplace incidents. The "National Gas Accident Analysis Report (First Half of 2024)" recorded a total of 181 gas-related incidents, resulting in 13 fatalities and 28 injuries.

INDUSTRY DEMAND

01. Industry Background

• Coal Mining Industry: Due to the high risk of gas explosions, there are stringent requirements for methane monitoring equipment regarding precision, alarm thresholds, and response time. The alarm threshold is typically set low to provide timely warnings, and the equipment must be precise enough to detect even slight changes in concentration.
• Oil and Gas Industry: The primary focus of methane monitoring is leak detection in pipelines and storage facilities, emphasizing the device's remote detection capability and sensitivity to minor leaks.
• Landfills: The key focus is on the overall methane emissions across large areas, with standards prioritizing the monitoring equipment’s coverage range and long-term stability.
• Greenhouse Gas Research: Methane monitoring standards in this field emphasize data accuracy and consistency for global comparison and analysis.

02. Policy Background

• "14th Five-Year" National Emergency System Plan: This plan provides guidelines for building emergency management systems, offering general guidance for real-time monitoring, timely warning, and effective handling of critical urban infrastructure, such as gas pipeline safety monitoring.
• Methane Emission Control Action Plan (Issued November 7, 2023): Jointly released by the Ministry of Ecology and Environment and 10 other departments, the plan includes exploring pilot projects for methane emissions monitoring, promoting methane source monitoring in key sectors. This aims to gather data and insights from selected industries, areas, or sources, laying the groundwork for wider implementation in the future.

PRODUCT INTRODUCTION - GF370 GIMBAL-MOUNTED LASER METHANE REMOTE DETECTOR

1. Product Overview

The GF370 Gimbal-mounted Laser Methane Remote Detector offers rapid and reliable methane leak detection. Utilizing laser measurement technology, it adapts effectively to complex environments, providing comprehensive, 360-degree, no-dead-angle monitoring. The system configuration allows for preset positions, enabling automatic scanning, automatic patrol, and power-off memory functions.

2. Working Principle

The GF370 utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS), based on the gas absorption theory of the Lambert-Beer law. This technology leverages the narrow linewidth and current-tuned wavelength properties of a tunable diode laser. By modulating the laser wavelength and emitting a specific wavelength range of detection laser, gas molecules absorb the modulated probe laser. The concentration of gas molecules is then measured according to the amount of absorption.

3. Product Features

• Long-distance Detection: Maximum monitoring distance reaches up to 200 meters.
• High Sensitivity and Fast Response: Quickly detects changes in methane concentration, providing timely warnings for potential leaks.
• Integrated Design: Equipped with an HD camera and omnidirectional variable-speed gimbal for multifunctional monitoring.
• Intelligent Monitoring: Supports automatic scanning, automatic patrolling, and power-off memory functions, reducing the need for manual operations.
• Robust System Capabilities: Generates inspection reports, recording gas concentration and alarm information.
• 3D Positioning and Target Capture: The high-precision camera supports 3D positioning, enabling quick targeting and capture by simply framing the target with the mouse.
• Outdoor Adaptability: Equipped with a wiper and sunshade to ensure proper operation in outdoor environments.
• Explosion-proof Design: Features a wide voltage operating range and surge protection, suitable for hazardous gas and dust environments.
