5. ARD2 000 Remote Methane Leak Detector User Manual 2 1. Introduction ARD2000 Remote Met hane 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, t he 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 do es not need to place th e 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 metha ne, 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 gase s, which greatly impro ves 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:

19. ARD2 000 Remote Methane Leak Detector User Manual 16 ☆ Common misuses The detecting laser is facing the s ky, and the light signal cannot be returned; The detecti ng laser is directed at the glass at a vertical angle, and the optical signal interferes, causing a false alarm. Therefore, there must be a certain angle with the glass when testing through the glass; During the detection, the moving speed is too fast, causing a sudden change in the signal and easily causing false alarms; The detection distance is less than 1 meter. At this time, the laser optical system is in a poor state. Try to avoid measuring in th is state. ☆ When there are factors that cause rapid gas diffusion, such as high winds and high temperatures, the gas cannot be concentrated, which affects the detection effect. Operators should consider similar situations in actual operations. ☆ ARD2000 Re mote Methane Leak Detector can detect methane leakage at a limit distance of 150 meters. The actual detection limit distance will vary depending on the environment. The longer the distance, the weaker the reflected laser energy and the lower the accuracy o f the detection result. When abnormal changes in the alarm value are found at a long distance, you should move to a close distance and check carefully. ☆ When the detecti ng laser is blocked by some objects, the distance will be abruptly changed, and false alarms may occur. ☆ When detecting a corner against a high reflectance background, two reflective indicating laser pointers can be observed. At this time , false alarms may be caused, and

18. ARD2 000 Remote Methane Leak Detector User Manual 15 4.4.2 M easuring When the laser emitted by the device passes through the natural gas leaking air mass, the methane gas will absorb the laser. The absorbed laser light is received by the detector through diffuse reflection, and the concentration information of the methane gas leakage is obtained through data collection and processing. Methane cylinder density (ppm ﹒ m) means: methane concentration (ppm) × air mass thickness (m). ☆ In order to ensure that the ARD2000 Remote Methane Leak Detector can properly measure methane gas, the following conditions must be met: There is methane gas accumulation in the laser path; The laser can pass through the gas; The lase r can be reflected back to the receiver through the reflective surface; ☆ During the detection operation, the moving speed of the handheld detector will also affect the detection result. Please observe the following points during operation: You should try to maintain a uniform moving scan; Focus on the detection of leaking valve ports, exhaust ports, cracks, etc .; When the position of the pipeline is known, detect according to the S - shaped scanning path;
