For years, reducing gas leaks on aging infrastructure has posed a significant challenge for the natural gas industry, particularly in the downstream (distribution) marketplace. Heath’s Discover AMLD™ aims to tackle this issue by effectively reducing methane emissions through the precise identification of gas leaks, with a minimal occurrence of false positives and negatives when compared to competing technologies. Discover AMLD is a cutting-edge technology employing open-air fixed-path Mid-IR Tunable Diode Laser Absorption Spectroscopy (TDLAS). Its impressive resolution reaches the part-per-billion (ppb) range for both methane and ethane. The inclusion of ethane detection enhances its ability to distinguish between pipeline gas and naturally occurring biogas. The Discover AMLD system is comprised of proprietary software running on a tablet that wirelessly interfaces with the gas detection unit, GPS, and anemometer which can be easily installed or removed from a vehicle. These components have been meticulously designed to necessitate minimal modifications to the vehicle and to harness the latest in wireless technology. Overall, Discover AMLD represents a pioneering solution for addressing the long-standing issue of gas leaks on aging infrastructure, setting new standards for accuracy and efficiency in the natural gas industry.

Heath's innovative Discover AMLD™ Off-Road reduces methane emissions through the identification of gas leaks while minimizing false positives and negatives compared to competing technologies. Discover AMLD™ Off-Road is an open-path system utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS). With a resolution in the part per billion (ppb) range for both methane and ethane, our system can detect even the smallest leaks. Ethane detection also helps to determine whether a detection is pipeline gas or naturally occurring biogas, improving accuracy and reducing false alarms. Our system's sensitivity levels, combined with a proven detection algorithm, can identify and distinguish between a pipeline gas leak and a non-pipeline gas leak, such as sewer, landfill and soil biogas sources. With Discover AMLD, you can be confident in the safety of your infrastructure and the reduction of harmful methane emissions. Discover AMLD consists of a vehicle equipped with the detector, GPS, anemometer, and proprietary software loaded onto the vehicle’s computer/tablet. All components were designed to require minimal modifications to the vehicle and utilize the latest wireless technology. The Discover AMLD analytical method improves the reduction of false positives and increases the accuracy of detection. Field testing has shown a greater than 95% probability of detecting gas leaks. Discover AMLD’s Graphical User Interface (GUI) streams your data directly to a secure cloud, which can analyze and process the data in real-time to produce actionable reports.

For mobile DP4 or mobile DP-IR leak survey you will need a Mobile Kit. The kit is mounted at a suitable point inside the vehicle. This unit may be powered by the vehicle electrical system by means of a cable/plug which is included in the mobile unit installation kit. The sample system made up of two or more rubber cones hanging down from the bumper about 1½” – 2” from the pavement, to sample the atmosphere as close to the surface of the ground as possible. This system picks up a continuous sample at the surface of the ground at points selected by the driver, and conveys it by means of tygon tubing to the Gast pump.
