This system is used to check the gas leakage in urban areas. Leakage detection is easily carried out when driving along the street where the pipeline is underground at a normal driving speed. With 2 separate laser detectors, the system can detect the leakage in front and at the side of the street.
The system consists of VMLD700II pump sampling laser detector in the front, VLD200 on the roof, controller in-car and remote monitoring platform. GPS and GIS technologies are adopted to exactly locate the leakage point and to upload the detection result to the remote monitoring platform.
