Product Overview Gas Leak Detection

 

Remote Gas Leak DetectionPERGAM is a leading manufacturer and supplier of remote leak detectors for the natural gas industry. Our technology is based on the principle of absorption infrared spectroscopy using a diode laser with tunable frequency. Together with our patented algorithm, it can determine the gas concentration. This allows remote and real-time gas leak audits; features that no other technology provides. The deliverable is a comprehensive report that can be used to plan measures and to provide proof of inspection with historical data.

All our systems have an automatic self-check during the boot-up process and a frequent concentration check of the built-in reference cell, as well as, auto-calibration during operation to ensure guaranteed performance.

As inventor of ALMA and SELMA, one of the most efficient gas leak detection technologies in the market, we also offer inspection services. Natural gas companies and other gas handling entities can benefit from our professional inspection services for their distribution, as well as,  for their transmission and gathering pipelines.

ALMA Aerial Laser Methane AssessmentALMA (Aerial Laser Methane Assessment) is operated on helicopters and is mainly used for transmission and gathering pipeline inspections. It provides reliable inspection results for underground as well as for above ground pipelines. It allows a safe flight altitude and doesn’t require specific weather conditions, contrary to other technologies in the market. The gas concentration is recorded along with a georeferenced video of the right-of-way. Severe leak indications can be reported real-time from the on-board flight engineer. ALMA was awarded type certification (STC) by the European Aviation Safety Agency (EASA) in 2011, by the Federal Aviation Administration (FAA) in 2013 and by Transport Canada in 2015.

Together with our constantly growing worldwide helicopter partner network, we provide economical and outstanding inspection service to the natural gas industry.

SELMA Street Evaluating Laser Methane AssessmentSELMA (Street Evaluating Laser Methane Assessment) is designed for use on all common vehicle platforms. SELMA’s main application is leak detection on natural gas distribution pipelines and city networks. We brought the highly sensitive technology known from our aerial gas detection system, ALMA, down to street-level. The unique two-sensor systems allow for the surveying of pipeline underground in the street and in the side walk. Two independent laser systems monitor the driveway (SELMA MPB – bumper laser) and the sidewalk (SELMA Roof).  SELMA MPB and SELMA Roof can operate simultaneously as well as separately. Through the outstanding sensitivity we can identify the smallest leaks at normal driving speed. A thought-out work flow, a simple installation (on many types of vehicles), and a semi-automated reporting function makes this concept the first choice for vehicle-based gas leak surveys.

LMS - Laser Methane StationaryLMS (Laser Methane Stationary) is the extension of our proven laser methane assessment product line and fills the gap for stationary applications. It can be used in refineries, natural gas storage tank farms, compressor stations and other facilities with potential methane leaks that need constant leak monitoring. Target points for the leak detection are pre-defined in the user-friendly software and the LMS system runs 365/24/7 to check for emissions. An alarm message with concentration and location (via text message or email) is triggered if a threshold is exceeded. The system comes with an aligned high-definition camera system and can be easily integrated in existing SCADA environments.

LMm-BE + AndroidThe LMm (Laser Methane mini) is our truly portable leak detector. Not much bigger than a cell phone, the LMm works on the same principle as our other laser methane assessment products. Through the remote detection capabilities, it is the perfect tool for hard-to-reach locations like pipes, in shafts, or under the ceiling.
Ideal for outdoor use, the green laser provides excellent visual tracking – even in bright sunlight.   A complementary app running on an Android mobile phone or tablet records the measured values in conjunction with the GPS position. The app shows the survey history and the measured locations on the map.  All reports can be shared by email within seconds (Model SA3C32A-BE).
For hazardous areas like coal mines, we keep an intrinsically safe version (Model SA3C32A-NE) available (limited communication and guide laser capabilities).

Microdrone LMC for web

 LMC (Laser Methane Copter) is the world’s first sensor for UAVs (Unmanned Aerial Vehicles) to detect and measure methane gas. Whenever the gas detection project is too small to mobilize a helicopter and a walking survey is too demanding, the LMC is your reliable and handy assistant. The LMC sensor is designed to fit on a large variety of UAVs / drones. The basis for the sensor is our proven Laser Methane mini instrument. Its’ light weight,  calibration-free operation and  data recording are only three its many advantages . The on-board LMC data unit records both, the track flown and the gas concentration. Post-survey, the data is immediately available for reporting and can be easily exported into a comprehensive leak survey report.
