MicroGuard

Portable natural gas leak detection solution - MicroGuard

The combination of high sensitivity, fast response, digital analyses and geospatial mapping allows MicroGuard™ to detect more leaks faster than ever before.

Leak surveyors no longer need to use slow, outdated and insensitive equipment to detect gas leaks within distribution pipelines, storage facilities, or anywhere within the natural gas infrastructure. With MicroGuard™, walking surveyors can pinpoint leak locations as well as generate and share comprehensive digital reports within minutes. It can detect, locate, map and quantify natural gas leaks faster and more reliably than traditional equipment.

This unique, portable gas leak detection solution comprises ABB’s LGR-ICOS™ ultrasensitive gas analyzer, a ruggedized phablet (large phone/tablet) with GNNS capability and high-brightness screen, ergonomic air sampling wand, and ABB’s proprietary MicroGuard™ software. MicroGuard’s advanced software provides a rich graphical user interface, a computational platform for geospatial mapping and advanced analytics, and automatically produces investigation reports compatible with all major geographic information systems.

Features and benefits
  • Fastest, highest sensitivity gas analyzer
  • Records data within 60 seconds after power on
  • Integrated sampling wand and UI
  • Ruggedized phablet with day-readable screen
  • Methane and ethane measurements provide sourceattribution
  • Data reported at 10 Hz with high sensitivity
  • No cross interferences
  • Fast gas flow response (2.5 Hz, 1/e)
  • Multiple data outputs
  • Secure internet connectivity

All LGR Analysers now come with a 2 Year Warranty as standard, underlying the quality and robustness of their manufacture and high reliability. Warranties can also be extended to 3 or 4 years at additional cost, at the time of purchase. Please enquire for further details.

Under normal operation and for the vast majority of applications, LGR Off-axis ICOS gas analysers require the minimum of servicing and maintenance.

One of the many benefits of this technology is long-term unattended reliability in the field.

LGR Advantages

Annual maintenance would normally include an inspection of the internal pump (or external pump if fitted) and the replacement of the pump diaphragm and valve seals if necessary.

This can be carried out by the user themselves or by ET either on site or back in the ET workshop (for a maintenance quote, please contact us).

ET recommends that LGR Analyser users consider the purchase of a field maintenance kit which includes:

  • Replacement solid-state hard-drive with LGR operating system and specific system files pre-loaded, for quick and simple swap-out in the field if ever necessary.
  • Pump maintenance kit (internal) to include spare pump diaphragm and valve seals.
  • Mirror cleaning kit.

Please contact us if you would like to receive a quote for the field maintenance kit.

Additional maintenance will be required for the LGR Liquid Water Isotope Analyser (LWIA) and Auto-injector unit and also the LGR Dissolved Gas Extraction Unit (DGEU).

For these instruments, please refer to the operation manual supplied with these instruments.
