ABB Ability™ Mobile gas leak detection system


The MobileGuard solution detects, maps, quantifies and localizes natural gas leak emissions while driving.


Find leaks fast

  • Performs measurements while driving at speeds up to 55 mph (88 kph)
  • Survey mains and services with the same drive by
  • Identifies attributes of emissions sources by measuring methane and ethane simultaneously
  • Shares survey data with MicroGuard™ to enable pinpointing of leak emissions sources in minutes

Find more leaks

  • ABB’s patented technology uniquely combines high sensitivity and accuracy with ruggedness and reliability.
  • Reports both methane and ethane simultaneously to eliminate false positives
  • Ultra-high (single parts-per-billion) precision and sensitivity allows detection of dangerous buried or hidden leaks and from distances up to 600 feet away.
  • No need for high-pressure gas cylinders on board (in contrast to other laser-based systems).
  • ABB’s proprietary algorithms (fluid dynamics models) combined with fast flow response yields accurate leak localization and size estimates.
  • Unparalleled data integrity and cyber security: ABB systems satisfy cyber security requirements and ABB customers own all data.
  • MobileGuard™ can share data with ABB’s MicroGuard™ to pinpoint leak locations in minutes

Data delivered immediately

  • Customer owns and always has access to all data
  • Data securely stored on the analyzer and in the cloud for immediate availability.
  • Electronic data facilitates compliance reporting and digital workflow
  • System communicates using 4G wireless technology
  • Data exportable to Geographic Information Systems (GIS)

Simple to use

  • Intuitive and easy to use user interface
  • Rich graphical display shows survey route, survey area, emissions indications and source attributes (i.e. Did emissions originate from a natural gas source?).
  • Records data within two minutes after power on (other methods either require 30-45 minutes to warm up or are over 1000x less sensitive).
  • Digital reports generated automatically in minutes after each survey.
  • Survey local distribution pipelines
  • Survey mains and services
  • Odor investigation
  • Construction verification
  • Post disaster evaluation 
  • Frost line evaluation
  • Survey large public gatherings

The LGR-ICOS technology advantages

The unique advantages of the patented LGR-ICOSTM technology make ABB’s gas analyzers the preferred choice.

Highest Precision and Sensitivity
Combines rugged, reliable near-IR diode lasers with an optical cavity to yield measurements with highest precision and sensitivity in a simple, robust package.

Widest Dynamic Range
Directly measures absorption in an optical cavity rather than only a cavity decay time. Thus provides linear response over a much wider dynamic range than conventional CRDS and TDLAS methods.

Best Performance 
Provides unsurpassed overall performance in every important metric (accuracy, speed, linearity, reliability).

Field Serviceable / Minimal Downtime 
Designed for ruggedness and reliability, in addition to performance. Overall simplicity allows easy service, if necessary.

Better Value
Analyzer performance unaffected by minor shifts in optical alignment enabling the use of simpler components and sub-systems.

Comprehensive Platform
ABB uniquely provides a comprehensive platform of solutions based on LGR-ICOS™ technology designed to address any leak detection application.
