Natural gas - an ideal energy: Natural gas is versatile, economical and environmentally friendly. Natural gas passes through underground pipelines from the sources to the distribution centers. All pipelines, transfer stations and other facilities have to be inspected regularly and conscientiously.
The new gas detector mounted on a car SELMA is designed for periodic review of technical conditions of underground pipelines in urban areas. In cooperation with local distribution companies, a methane detector has been developed which is based on the practical needs of the end user. This makes SELMA to a perfect tool for diagnosis of urban gas pipelines. SELMA can detect gas leaks in front and beside of the car. The system will output alarm when methane is detected. The included software generates a complete report which guarantees complete traceability.
The working principle of the methane gas detector is a pulsed laser diode beam. This technology guarantees no interference from other gases in urban areas where the air is saturated with various hydrocarbons (exhaust gases, etc.).
