As the government, enterprises and society pay more and more attention to the safety and environmental protection of gas pipelines, the safety inspection of gas pipelines, especially leak detection, becomes more and more important. Existing portable leak detectors require the probe to be placed in an environment with gas and be in direct contact with the gas. In the actual site, it is often difficult to reach the pipes or facilities, or even impossible to reach (such as inside the wall, in the flower garden, above the river, outside the riser of the tall building, inside the room, etc.). This makes the inspection efficiency of pipeline network leakage low or gives up inspection of certain pipe sections, which brings hidden dangers to the safety of gas pipelines. In response to this phenomenon, the Remote Methane Leak Detector came into being.


ARD2000 Remote Methane Leak Detector uses international advanced tunable diode laser absorption spectroscopy technology (TDLAS), which can detect methane gas within a certain distance. At the same time, through optimization design and independent research and development, the measurement distance and accuracy of the detector are greatly improved, which is the most powerful safety guarantee for gas inspection and leak detection. Unlike traditional portable detectors, this Remote 
Methane Leak Detector does not need to place the probe in a gas-filled environment. 
Instead, the device emits a laser beam. The laser passes through the pipe or the space above the facility and hits the object at the other end. Reflected back to the receiver, 
and then converted into electrical signals, these signals are used to analyze the concentration of methane, the unit is ppm﹒m. By using WMS technology, the ARD2000 Remote Methane Leak Detector can achieve extremely high detection accuracy. The light at this wavelength is only absorbed by methane, so it only reacts to methane and is 
not affected by other gases, which greatly improves the accuracy of detection.  Using the Remote Methane Leak Detector, the operator does not need to be in a dangerous 
environment, which not only protects the safety of the inspector, but also can inspect the overhead pipeline from a long distance, which improves the inspection efficiency. 
The detection reading is the product of the concentration of the laser passing through the methane gas mass and the thickness of the gas mass in ppm﹒m, as shown below:
