Close-Proximity Continuous Monitoring™

NevadaNano’s Close-Proximity, Continuous Monitoring™ (CPCM™) architecture enables MethaneTrack™ to locate the source and calculate the rate of emissions with much greater accuracy than other monitoring solutions operating from a greater distance, thereby significantly improving detection and quantification.

Close-Proximity Continuous Monitoring™ is a Breakthrough in Explosive and Flammable Gas Monitoring

The key to close-proximity monitoring is ‘Intrinsically safe’ instrumentation endpoints.  Intrinsically Safe means that MethaneTrack™ endpoints are engineered to prevent the ignition of flammable gases or vapors at explosive & flammable concentrations.

MethaneTrack’s intrinsically safe certification ensures that the endpoint does not pose an ignition risk in the most hazardous locations (Zone 0, C1D1), making it the perfect choice for close-proximity monitoring in environments where safety is paramount. Close-Proximity Continuous Monitoring™ is the ability to place intrinsically safe endpoints near potential emission locations to measure the gas concentrations near the source. This results in greater location and quantification accuracy, as the short distance from the source to the endpoint decreases the impact of wind variations between the source and any more distant detector. 

The figure below shows how Close-Proximity increases the gas concentration by up to 500 times due to reduced gas dispersion by the wind resulting in improved detection and quantification. In addition, the short distance between the source and the endpoint enables tighter location accuracy.

The Secret Weapon: Close-Proximity Continuous Monitoring™

The image titled "The Secret Weapon: Close-Proximity Continuous Monitoring™" from NevadaNano presents the benefits of CPCM™ (Close-Proximity Continuous Monitoring) enabled by intrinsically safe endpoints. The left side of the image lists the advantages of close-proximity sensing, which include: Higher gas concentrations Lower false positives More accurate location detection The ability to distinguish between fugitive emissions and operational emissions Improved quantification The right side features a graph titled "CH₄ Concentration vs. Distance" (for a 40 SCFH or 0.8 kg/hr leak) that illustrates how methane concentration (ppm) decreases with increasing distance from the source (meters). A close proximity sensor is shown to detect significantly higher methane concentrations (10-500 times greater) near the source, emphasizing the efficiency of close-proximity sensing.
