Rapid Leak Detection and Grading for Safer Gas Distribution

Pinpoint underground methane leaks quickly, classify their severity, and reduce safety risks with field-ready instruments built for utility crews.

Built for PHMSA and Beyond

Methane management across utility and distribution networks is shifting from leak detection to quantitative verification. Regulators and operators alike are demanding defensible data that meets emerging expectations from PHMSA, OGMP 2.0, and voluntary methane programs.

Sensors, Inc's suite of tools supports this transition, enabling field teams to measure methane concentration and flow directly at the source, under real operating conditions.

Applications

Available in multiple HazLoc configurations, these systems integrate safely into utility operations across the full distribution chain.

  • Pipeline Leaks and Excavations — Quantify leak rates during maintenance or after repair to document performance and validate mitigations.
  • Bar Holes and Pavement Interfaces — Draw controlled gas samples to measure methane concentration gradients beneath the surface.
  • Regulator and Meter Sets — Characterize venting from relief valves, pilots, or diaphragm housings to improve inventory accuracy.
  • Service Line Blowdowns and Purges — Quantify controlled emissions during tie-ins, pressure tests, or commissioning events.

Bar Hole Sampler

Integrating pinpointing, purging, and quantification in one compact tool, the Bar Hole Sampler enables rapid leak detection and real-time measurement for accurate grading and PHMSA-aligned reporting—streamlining utility fieldwork with unmatched efficiency.

SEMTECH® HI-FLOW 2

Building on decades of emissions measurement expertise, the SEMTECH® Hi-Flow 2 delivers direct, high-accuracy leak quantification from 0.0005 to 25 CFM (0.015–700 lpm) with ±5% accuracy. Its integrated TDLAS methane sensor and high-volume sampling system capture and quantify total emissions in real time—eliminating cross-gas interference and extending both low- and high-range performance beyond legacy LDAR tools. Compact, portable, and field-proven, it’s engineered for precise, defensible data in modern methane management programs.

The Results

Powerful, Transparent Reporting

All sampling data is stored in a secure, queryable SQL database that gives users instant access to records, run histories, and audit trails. Default report templates summarize sample runs, flow totals, and QA/QC checks, while advanced users can build fully customized reports to match internal or regulatory requirements.

The result: fast, defensible documentation—ready for analysis, compliance, or stakeholder review.
