L10 100m Remote Laser Methane Detector for City Gas Pipeline Inspection

Product Specification

Product Overview

The AiLF L10 100m Remote Laser Methane Detector is a portable solution designed for rapid, non-contact methane leak surveys across natural gas pipeline networks, urban gas infrastructure, and industrial facilities. With a detection distance of up to 100 meters, it allows operators to investigate suspected methane leaks from a remote position, helping reduce the need to approach potentially hazardous areas during routine inspections.

Powered by Tunable Diode Laser Absorption Spectroscopy (TDLAS), the L10 emits a laser beam tuned to methane's characteristic absorption wavelength. As the beam passes through a methane plume and reflects from a suitable target surface, the detector analyzes the returned optical signal to identify methane absorption. The instrument displays measurement results in ppm·m, representing methane concentration integrated along the optical path.

Designed for efficient field operation, the L10 offers a response time of less than 0.1 seconds, adjustable audible alerts, and visual alarms. Its long-range measurement capability enables inspectors to survey suspected leakage points efficiently, while the absence of a dedicated reflector panel requirement in the stated configuration supports flexible inspection workflows where suitable reflective surfaces are available.

The L10 also supports Bluetooth connectivity with AiLF's ADA mobile software. Operators can record GPS-linked readings, add inspection notes, and capture photos of monitored components and suspected leak locations. These functions help organize inspection records, support leak detection and repair (LDAR) workflows, and simplify subsequent maintenance reviews.

Key Features and Benefits

1. Long-Range Detection up to 100 Meters

The L10 can detect methane from distances of up to 100 meters (approximately 328 feet), making it suitable for surveying selected pipeline sections, gas distribution facilities, and other hard-to-access inspection points.

2. Fast Response for Efficient Leak Surveys

With a stated response time of less than 0.1 seconds, the detector provides rapid measurement feedback, helping inspectors scan target areas and investigate potential methane leaks with greater efficiency.

3. High Sensitivity at 5 ppm·m

The instrument offers a stated sensitivity of 5 ppm·m. This path-integrated measurement helps identify methane along the laser beam path and supports the investigation of low-level gas plumes under suitable operating conditions.

4. TDLAS-Based Non-Contact Measurement

The L10 uses laser absorption spectroscopy to identify methane through its characteristic optical absorption. Remote measurement enables inspection without placing the instrument directly against the pipeline or suspected leak point.

5. Audible and Visual Alarm Functions

User-configurable audible alerts and visual alarms help notify operators when methane is detected, supporting prompt investigation during routine patrols and leak surveys.

6. Bluetooth Connectivity and Digital Inspection Records

The detector connects to the ADA mobile application via Bluetooth, enabling inspectors to associate measurement readings with GPS location information, notes, and field photographs. This supports better documentation and traceability throughout the inspection process.

7. Portable Operation for Field Inspections

The handheld design supports mobile inspection tasks across pipeline networks and industrial facilities. The stated operating characteristics include a battery runtime exceeding 10 hours and no warm-up or cool-down period required for normal measurement operation.

How TDLAS Remote Methane Detection Works

TDLAS is an optical sensing technique that analyzes how gas molecules absorb laser light at specific wavelengths.

During an inspection, the L10 directs a laser beam toward a suitable target. If methane is present along the optical path, methane molecules absorb part of the transmitted light. The returned signal is then analyzed to determine the methane-related absorption.

The resulting measurement is displayed in ppm·m, allowing inspectors to identify potential methane plumes along the beam path without directly contacting the gas source.

By combining wavelength-selective laser sensing, rapid signal analysis, and remote optical measurement, the L10 supports practical methane leak inspection across a range of field environments.
