The necessity of methane leak inspection
Methane is a component of natural gas and is primarily used as an industrial fuel source and chemical feedstock. It is usually harmless if stored properly, but the consequences of a leak can be serious. Methane is an explosion hazard in enclosed areas; liquefied methane floats on water and boils, producing vapor clouds that are also flammable and can produce toxic gases when on fire.
The hazards for workers working in the leakage area should not be underestimated. High concentrations of methane can reduce the amount of oxygen breathed from the air, causing mood changes, slurred speech, vision problems, nausea, vomiting, facial flushing and headaches. In severe cases, breathing and heart rate changes, balance problems, numbness, and confusion may occur. Therefore, timely monitoring and early warning of methane gas leakage is particularly necessary.
The Purway CH-4 laser methane detector has the characteristics of high sensitivity, high measurement accuracy, low detection limit, fast response speed, and requires almost no maintenance and calibration of on-site measurements.
Compared with traditional electrochemical sensor detection methods, the laser methane detector can achieve non-contact measurement and quickly detect trace amounts of methane gas in the air. The longest detection distance can reach 300 meters, and it is not affected by environmental factors such as temperature, humidity, and pressure. It has Very high stability.
The Purway CH-4 laser methane detector is a lightweight natural gas leak inspection load.
The load uses Tuned Diode Laser Absorption Spectroscopy (TDLAS) technology to detect methane (CH4) components in the air and is integrated on the UAV system to achieve non-contact detection. The load also integrates a visible light sensor and a laser rangefinder to realize visual inspection and accurately locate the leak point coordinates in real time.
